Simulate rotor dynamics, be more productive Simcenter™ Femap™ software is a versatile finite element analysis (FEA) pre-/postprocessor for robust meshing and model definition , interoperability with Simcenter Nastran and other popular solvers, and overall ease-of-use. Simcenter Femap is an ideal solution when you need to use a traditional mesh-centric approach. What does mesh-centric mean? This means you can easily work with legacy FEA models that might not have the original geometry that was used to create them. For example, you might import an old bulk data file, and with Simcenter Femap, you can easily re-use and make edits to that mesh. In 2023, Simcenter Femap continues this trend by introducing key features and updates to enhance your productivity and collaboration, streamline your modeling processes for geometry, meshing, analysis, and postprocessing. Highlights of the new enhancements introduced in Simcenter Femap versions 2301 and 2306: The products you engineer experience a wide array of phenomena, and you need tools that can help you efficiently model and simulate what is happening to your products before you build them. Simcenter Femap helps you create the FE models needed to accurately simulate product performance. These new enhancements will help you solve even more complex problems. Create rotor dynamics models for Simcenter Nastran Rotor Dynamics If you're engineering rotating machinery, then the latest release of Simcenter Femap is for you. In 2023, Simcenter Femap introduces support for Simcenter Nastran Rotor Dynamics (SOL 414) so that you can more efficiently create rotor dynamics models. Add or remove elements during a nonlinear solve Sometimes when performing a nonlinear analysis, you need the option to remove or add elements to the model as simulating to accurately capture behavior, such as when a material might have completely failed when something is bending. In 2023, Simcenter Femap introduces the ability to define element addition and removal for nonlinear simulations using Simcenter Nastran Multistep Nonlinear solution SOL401. Capture additional key results data not calculated by the solver with computed vectors Solvers create a lot of data, but even still, your solver might not give you the specific metric you need for your application. Exmaples can include failure theories or envelopes of results. Simcenter Femap introduces Computed Vectors in 2023 which let you calculate the key results you need that the solver doesn’t provide in its result file. Meshing finite element models can be a tedious process. Simcenter Femap provides the tools you need that help make this process go faster. The following enhancements introduced into Simcenter Femap in 2023 help make you more productive so you spend less time on meshing and modeling and more time on engineering. Use mesh points with Body Mesher Many times, you might need to force a node on your mesh to be at a certain location. In 2023, the Body Mesher command in Simcenter Femap now recognizes hard points. The helps you ensure nodes are placed at the specific locations needed when you initially create the mesh and reduces extra time needed go back and maually edit node locations. Update line elements connected to other element types using the Mesh / Mesh on Mesh command n some finite element models, you might use a line element as a stiffener, which could then be connected to a shell mesh in your model. During the CAE process, sometimes you may want to refine or coarsen your shell mesh. But this action could pose a problem to the connectivity of your line elements. In 2023, Simcenter Femap allows you to update line elements at the same time as you refine or coarsen the model. This saves you time so you don’t need to perform multiple meshing operations and also ensures your model maintains connectivity. Quickly create mesh to connect different regions of your model, regardless of complexity Sometimes you might have different sections of your mesh that might not be connected together. Simcenter Femap now gives you an easy way to quickly create a mesh that connects these sections together, regardless of the complexity of the shape of the model. Find the right command quickly Simcenter Femap has been around for over 30 years, and so there are a lot of commands and functionality that have built up over that time. This means finding the right command can sometimes take time. In 2023, Simcenter Femap now includes a Command Finder that can help you get to the command you need just by typing in a few keywords. ​ In many organizations, the simulation team seems to exist in a world of its own, disconnected from the broader design and development process. However, it’s important for the simulation team to be tied to the broader digital thread across the organization so that simulation engineers know they are simulating and providing feedback on the latest designs. New capabilities introduced in 2023 help Simcenter Femap users stay integrated with development: Create and manage Femap files directly in Teamcenter Too often, simulation engineers work outside of a the PDM system used by the rest of the organization to track designs and configurations. This can easily lead to mix ups where engineers don’t simulate the right version of a product release, or simulation results get lost in the shuffle. In 2023, you can now directly manage Femap files in Teamcenter directly from the Femap interface. This means you can make sure the organization knows which simulation files were used for a particular design. Improved monitoring when solving multiple analysis sets at once Simulation teams are very busy, often working on multiple projects or multiple analyses at the same time. As a result, keeping track of the status of multiple analyses can be a challenge. New enhancements to the Analysis Monitor in Femap help you more easily understand the status of simulations you’ve launched from within Femap. In addition, new commands in the Analysis Monitor help you take appropriate action at the click of a button. Interested in learning more about what's new and improved in Simcenter Femap in 2023?

Create your own material model One of the main challenges in Computer Aided Engineering (CAE) simulations is accurately representing the complex behavior of real-world materials. This accuracy is especially crucial in multiscale simulations, where the accurate response on a global scale depends on the detailed mechanical representation of each microconstituent and its interfaces. To meet the needs of designers working with parts that have complex microstructures or advanced new materials, the Simcenter Multimech 2306 enables users to create their own material models through user-defined subroutines in C or C++. Engineers and researchers have traditionally faced difficulties related to the modeling of advanced materials. Standard material libraries often do not cover the full range of materials used in different industries and products, which often forces engineers to compromise their material models and accept some inaccuracy in the results. Furthermore, not all CAE tools support user-defined materials in multiscale simulations, where some or all microconstituents require custom materials. Support for user-defined custom materials in Simcenter Multimech offers a powerful solution to these challenges. Custom materials can be applied in different types of simulations, whether in global scale part models, microstructural scale virtual tests or True Multiscale simulations. First example: fatigue in adhesive joints Adhesive materials have a different mechanical response when compared to common engineering materials such as metals. Furthermore, its response varies widely depending on factors such as composition, humidity and temperature. Simulating models containing this type of material is an excellent example of the effectiveness of Simcenter Multimech's custom subroutines. A specific case involves the cyclic loading of an adhesive joint with gradually increasing load. A custom constitutive relationship, specially developed to model the adhesive behavior under fatigue, was coded and applied to the adhesive elements. The results demonstrate how the subroutine captures the different fatigue responses in each condition, also identifying the areas most susceptible to fatigue failures. Second example: custom fault model with gradual stiffness reduction The example above shows a single-scale use of the new feature, as no microstructural features were modeled. That is, the complete model is in the scale of the components and the adhesive joint. However, user-defined subroutines can also be applied in multiscale analyses, to model the response of specific microconstituents. A powerful example of this new feature in a multiscale simulation is the creation of a user defined failure criterion. A common application for failure criteria in CAE simulations is to reproduce phenomena such as fracture, cracking or detachment, reducing the stiffness of elements to almost zero if a specific criterion is met. In this case, the path of the reduced stiffness elements represents the fracture path. Although failure models exist in most CAE tools and have been used for decades, convergence is a common challenge: abrupt reduction in stiffness can lead to higher residuals, requiring careful mesh selection, time lag strategy, stabilization etc. , users can develop a failure model in which the stiffness is not immediately reduced, but gradually decreases over several time steps. The figure and animation below demonstrate how the gradual decrease in stiffness occurs: The result of custom failure criteria in a real multiscale simulation is an improvement in the convergence of the nonlinear analysis, leading the simulation to progress much further than using a simplified failure model. Extended results allow users to perform post-failure investigations, showing how the component under investigation behaves after each localized failure mechanism has occurred. Unlimited possibilities with your own material models The examples shared above demonstrate just a fraction of the potential that can be unlocked by customizing material models in Simcenter Multimech. Other application examples include: Temperature dependence and strain rate in metals Custom multiaxial damage and fault models Low-cycle fatigue on microstructural components Mechanical response of unusual materials such as glass, sand, cardboard, wood, etc. Furthermore, as far as multiscale simulations are concerned, material subroutines in Simcenter Multimech can be used at microstructural scale along with global scale models solved in Simcenter 3D in different solvers such as Nastran, Samcef, Abaqus or Ansys. This means that it is now possible to code material subroutines that work with any of these solvers in C++, instead of their native Fortran programming. For users struggling to meet expectations due to material complexity and inaccuracies caused by incorrect material modeling, user-defined models in Simcenter Multimech are a tangible solution. Comprehensive guidance and examples of code, compilation, and usage are provided in the Simcenter Multimech documentation. Opportunity: Increasingly, advanced computer simulations can be used to reduce costs and shorten the timeframes of R&D projects that were previously only based on physical experiments. Simcenter Multimech is an excellent example in this direction. With the use of intensive simulation in the conceptual stages of the development of new materials, we can be more assertive in the construction of performance proof experiments!

Becker Marine helps ship owners realize up to 6 percent annual fuel savings by using Simcenter STAR-CCM+. Becker Marine Systems Becker Marine Systems is the market leader for high-performance rudders, maneuvering solutions and energy-saving devices for all types and sizes of vessels, including yachts, container ships and large cruise ships. With headquarters in Hamburg, Germany, the company employs over 200 specialists worldwide at offices located in Germany, China, Singapore, Korea, Norway and the United States. http://www.becker-marine-systems.com Headquarters: Hamburg, Germany Products: Simcenter Products, Simcenter STAR-CCM+ Industry Sector: Marine From the moment we receive a new order, we typically have six weeks to find the required energy savings. This is a strict timescale, as the towing tank slot is reserved well in advance and cannot be moved. Steve Leonard, Head of CFD and Research and Development IBMV/Becker Marine Energy saving devices in the marine industry Energy efficiency is an important concern for ship builders and operators. The marine industry seeks to reduce vessel operating costs and meet CO₂ and NOₓ emission regulations. While modern, streamlined hull designs can help save fuel in new designs, most ships in service are older and lack these advantages. To meet this challenge, companies use custom Energy Saving Devices ( ESDs) on their aging vessels. These devices are positioned close to the propeller and can improve propulsion performance even on newer hull designs. To understand the potential savings for a shipbuilder, a vessel that is listed at a dead weight tonnage (DWT) of 55,000 will use about 160 tons of fuel per day at normal cruising speed. Over the course of a year, a 5 percent improvement in fuel consumption would save over 2,000 tons of fuel and result in cost savings of approximately $500,000, so it’s easy to understand why marine companies are anxious to apply measures that will enhance energy efficiency. The Becker Mewis Duct® for greater hydrodynamic efficiency A widely used ESD is the Becker Mewis Duct®, designed for slower ships altogether. Distributed by Becker Marine Systems GmbH & Co. KG, this device offers fuel savings at a given speed or allows the vessel to travel faster with the same power. The Becker Mewis Duct consists of an ESD with integrated angled fins, which produce a forward thrust, straighten and accelerate the flow of water on the propeller. These fins reduce losses in propeller airflow, resulting in greater propulsive thrust. For best results, duct properties and fin design are optimized for each hull shape, harnessing energy from the hull's frictional boundary layer to improve the vessel's overall hydrodynamic efficiency. The energy savings provided by the Becker Mewis Duct depends on the hull-to-block ratio and propeller thrust load. On average, fuel savings can vary from 3% for multipurpose vessels to up to 8% for oil tankers and bulk carriers. When combined with a Becker rudder, this savings can reach up to 8% for general ships. Furthermore, the use of an ESD such as the Becker Mewis Duct can reduce NOₓ and CO₂ emissions, regardless of the ship's draft and speed. Using Simcenter STAR-CCM+ to design the Becker Mewis Duct IBMV Maritime Innovationsgesellschaft mbH (IBMV), a subsidiary of Becker Marine, develops innovative technological solutions for the maritime market. The team led by Steve Leonard, head of CFD and R&D at IBMV, used Simcenter STAR-CCM+® software to design the Becker Mewis Duct. Using Simcenter STAR-CCM+ allowed the team to discover better designs faster. The Becker Mewis Pipeline was introduced to the market in 2008 and the first full-scale installation took place in 2009. The estimated energy savings for this vessel was approximately 6%. “The success of the Becker Mewis Duct is very dependent on the Simcenter STAR-CCM+ CFD process that we use to define the duct,” says Leonard. “Without accurate CFD simulations, we cannot fine-tune each duct to the flow conditions specific to a particular hull. For each scenario, we use STAR-CCM+ to carefully adjust over 40 design parameters to create a unique duct. Although there are similarities, the duct that we design for each vessel is absolutely unique. No two ducts are ever alike.” The marine industry is known for its conservative approach, where self-propelled tests are used as a benchmark to assess vessel performance. Despite this, the IBMV team performs intensive computational fluid dynamics (CFD) calculations to design and fit each vessel's specific Becker Mewis Pipeline. These efforts are aimed at ensuring energy efficiency and minimizing fuel consumption during model testing. Most CFD calculations are performed at model scale, but the IBMV team also perform final full-scale calculations to ensure design accuracy and cavitation performance. Although an automated optimization process seems adequate, it is not feasible for the Becker Mewis Pipeline due to the complexity of the flow around the pipeline, which cannot be reduced to simple numerical parameters. Therefore, a team of experts visually inspects the data generated by Simcenter STAR-CCM+ to identify adverse characteristics and suggest improvements for the next iterations of the project. The experience accumulated over the previous studies allowed the IBMV team to define an initial project that serves as a basis for future improvements, seeking the ideal energy savings in about 10 design iterations. This approach results in well-engineered hulls, reducing energy waste and providing significant fuel savings opportunities through the Becker Mewis Pipeline. Leonard recalls one project in particular where the first iteration of the design achieved the required energy savings, a win for IBMV. Conclusion IBMV has delivered over 1,000 Becker Mewis Ducts, clearly demonstrating the value of engineering simulation, in particular CFD, in the marine design process. Using CFD can help companies make informed decisions while also providing a constant stream of data to help shipbuilders improve real-world vessel performance. Without intensive design exploration driven by experienced engineers using Simcenter STAR-CCM+, it would be impossible for Becker Marine to deliver finely tuned energy saving devices that offer guaranteed performance while adhering to a strictly controlled schedule. By using Becker Mewis Ducts, customers have realized millions of dollars in fuel savings. The ESD has also played a significant role in reducing harmful CO2 and NOx emissions in the shipping industry as a whole. For example, when a Becker Mewis Duct was developed for the AS Valeria, a bulk carrier that weighs in at 57,000 DTW, the IBMV team used Simcenter STAR-CCM+ simulation capabilities to predict fuel savings of 5 percent, which was confirmed in sea trials; and they used further CFD capabilities to help achieve a reduction of 1,002 tons of CO₂ per year. For each scenario, we use Simcenter STAR-CCM+ to carefully adjust over 40 design parameters to create a unique duct.

Full integration of strength and fatigue with finite elements Reducing the burden on durability experts Analyzing strength and fatigue can be complex, but now there are tools that can streamline this process. It is possible to install various workflows for different groups and applications, starting with the existing models in Simcenter 3D, which encompass different strength and fatigue methodologies. These models are widely used today. However, it is important to note that there is always room for improvement. If some users in your company have provided feedback stating that the workflows are functioning well and producing the necessary results, but the Simcenter Specialist Durability tool seems to be geared only towards experts, it indicates that it is not being fully utilized. Many colleagues only use it when they need to sign off on their projects. You know that the tool is useful when looking at stress results, as it adds the influence of material strength to the stress result and immediately provides a meaningful result, namely the degree of utilization that the current project has. Getting involved The new SIEMENS tool is called The Strength and Durability Wizard. It is a tool that automatically connects to existing finite element results and pre-selects the active solution when there are multiple options. Additionally, the tool also pre-selects the type of load based on the solution, i.e., which type of load cycle should be analyzed: block load for single linear results or a transient series of results for non-linear results. With these pre-selections, you usually only need to verify this step. Tool tips at each step provide direct support to your workflow. In Simcenter 3D, you will find the pre-selections of the strength and fatigue assistant. In the second step, you can choose the type of analysis: strength, life, or stress-life. Here, pre-selection is also used to prepare the method parameters. Next, you can check the material or estimate fatigue parameters. All that is required of you is to press the "solve" button to make the post-processing available on the same page. In the end, you will see that you can reduce your workflow descriptions to a few mouse clicks and be confident that even non-regular users will feel comfortable with the workflow. Useful resources The tool is fully integrated with the Simcenter Specialist Durability tool. This means that a durability solution is created in the simulation file as soon as an analysis with the assistant is created and run. This can now be edited by the Assistant and the full durability tool. Therefore, we can easily enhance a strength analysis to a fatigue analysis using the assistant. Simcenter not only remembers that a particular solution was created by the assistant so that you can edit it with the assistant, but also cloned solutions inherit this property. Thus, with just a few clicks, mainly to change the analysis type and restart the solve. We can obtain all the results and analyze the fatigue behavior. We can even use our internal post-processing templates automatically. And since the assistant is fully integrated with the full durability environment, we can also start with an assistant-based analysis and add all the features that the durability tool offers. All of this will save a lot of time when creating new models and workflows. And for those who take pride in the reports they provide, they will be pleased to know that the produced results are in the same format as durability results. This means that you can now use the full set of post-processing tools. Additionally, an image created in the assistant is automatically created in the post-processing scenario. More usability for the specialist tool as well Resistance and durability experts will identify a series of minor yet beneficial improvements. As you explore the software, you discover the new models that allow you to select the results of the most useful functions. This functionality resembles the definition and selection of analysis models, being extremely helpful for your daily tasks. The predefined models reduce the need for additional clicks and shorten your workflows with different workgroups. Want to learn more about Simcenter 3D? Clique aqui!

Thermal Simulations in the LED Lighting Industry Simulating beyond thermal properties – material properties and semiconductor calibrations Executive Summary Celera uses Simcenter FLOEFD technology to accurately simulate the temperature at the LED junction and the heat spread over the components that make up the luminaire. The company also uses advanced characterization equipment, Simcenter T3STER and TerraLed, to improve the accuracy of CFD simulations of electronic components. These tools enable Celera to offer high-tech thermal management consulting services to various industrial sectors, providing specialized technical support and high-quality products Norbert Arthur Frauz Engineering Coordinator at Celera Introduction At Celera, we provide thermal management solutions for various industries, including high-power LED lighting. Celera Celera is a high-tech company that provides thermal management solutions for electronic devices and components in various industries, including the high-power LED lighting industry. Using advanced technology such as Simcenter FLOEFD software, Celera is able to accurately simulate temperature and heat flow in electronic components, allowing it to identify problems and provide effective solutions to ensure optimal performance and durability of these components. The company serves several leading companies in their respective industries in various countries, offering specialized technical support and high-quality products above market average. High-Power LEDs By using the FLOEFD software in conjunction with the precision of the results measured by Celera, we were able to identify a problem in an LED luminaire for horticulture that was causing the polycarbonate lens to burn out. Through thermal and fluid dynamics simulations conducted with FLOEFD and precise measurements using T3ster and TerraLed equipment, we were able to understand the behavior of the LED luminaire and identify the root cause of the problem. Simulations, results and tools Initially, it was thought that the problem was related to the excess heat generated by the LEDs. However, after characterizing the LEDs in the equipment, setting up the luminaire in the CFD (digital twin) software, and analyzing the simulation results, it was identified that the cause of the lens burnout was the cascade effect that occurred due to the absorption of a portion of the blue spectrum emitted by the LEDs by the polycarbonate lens. This led to a degradation process, which decreased its transparency, and consequently, more thermal energy was absorbed from the beam of light, leading to the carbonization of the lens and subsequent burning of the LEDs. Through this detailed simulation, which took into account not only electrical aspects but also material properties and photometric properties, it was possible to identify the real problem and find a solution to improve the LED luminaire, thus avoiding losses and customer dissatisfaction. Our client (Audax) sent us some luminaires so that we could measure the temperature at the LED junction after thermal stabilization. These luminaires underwent tests, and each of the blue, white, and red LEDs was individually monitored so that their maximum temperatures could be known, as seen in the photo. Additionally, each type of LED was tested in the TerraLed integrating sphere to determine its luminous efficiency, heat generation, and junction resistance up to the base of the printed circuit board. In these initial measurements, we already noticed that the junction temperatures were not very high and by themselves would not lead to lens melting. With these data obtained from empirical laboratory measurements, we characterized the FLOEFD simulation. Upon analyzing the simulation results, it was found that the simulation was faithfully representing the real luminaire operation, and that the temperatures in the luminaire were within a safe operating range. We then contacted the manufacturer of the polycarbonate lenses to obtain more information on the lens absorption properties. With these new curves, we characterized the material in the software and configured the wavelengths emitted by each of the LEDs and re-simulated. This time, the result was entirely different, and already during the simulation stabilization, the software informed us that the lens was melting. Upon analyzing the results, we saw that the lens was subjected to much higher temperatures than it could withstand, but not from the base of the LEDs, rather absorbed from the beam of light. Factors that affect the analyses The analyses performed with FLOEFD take into account various factors, including product geometry, operating conditions, materials, and thermal properties. These factors directly affect the flow and heat transfer conditions, which can be analyzed with FLOEFD. For example, in a luminaires analysis, the geometry and materials of the luminaire can affect temperature distribution and condensation/ice formation. Operating conditions, such as ambient temperature and luminaire power, also directly affect these results. Results and objectives of the analyses The results of the analyses performed with FLOEFD include detailed information about product performance, including flow, temperature, and heat transfer. These results can be used to optimize product design, improve energy efficiency, and ensure that the product meets regulatory and safety requirements. The objectives of the analyses include reducing product development time, improving product quality, and reducing prototyping and testing costs. Additionally, analyses performed with FLOEFD help increase confidence in product design, reducing the risk of failures and performance issues.

Multidisciplinary Optimization and Multiphysics Integration Hello everyone! Today we will discuss the most advanced technologies in the design of electric machines. CAEXPERTS, in partnership with SIEMENS Digital Industries Software, is implementing a new design workflow driven by multidisciplinary optimization and multiphysics integration for its clients in the electrification industry. Check it out! Integration of Simulation and Optimization Tools The integration of simulation tools and the use of optimization software have revolutionized the design of electric machines, enabling the creation of highly efficient and customized solutions for various applications. Simulation of complex systems and geometries enables the integration of the traditional motor design process with current computational power. Digital tools combine electrical, thermal, fluid dynamics, mechanical, and acoustic solvers, explore the optimized design space through algorithms, numerically validate calculations and theoretical models, integrate the product into the system, and automate processes. This allows designers to focus on the most challenging aspects of the design, drastically reducing the need for bench testing until the final prototype is developed. The intensive digitalization of product development engineering effectively reduces timelines and costs, resulting in more competitive and robust products. Advanced project workflow The design of electric machines begins with the definition of the problem to be solved and the desired design characteristics. The project requirements are converted into essential parameters, such as power characteristics, load demands, and dimensional constraints, which are input into the machine's design equations. Specialized software assists in this stage by translating the project requirements into desired numerical characteristics. Next, different motor topologies are compared by testing various configurations to determine the most suitable topology. An optimization software, such as HEEDS, can quickly evaluate a variety of configurations within minutes, using low computational cost analytical equations for comparative analysis. Coupled with an analytical solver like SPEED or Motorsolve, HEEDS explores the design space, presenting the characteristics of different topology combinations, such as a BLDC with internal or surface-mounted magnets, reluctance machines, or different slot geometries. This comparative analysis allows for the identification of the most promising options before proceeding to more detailed stages of the design. Analytical Calculation and 2D Analysis Analytical calculation plays a fundamental role in the design of electric machines, enabling the rapid evaluation of parameters. Equations and mathematical models are used to obtain important characteristics such as efficiency maps, torque curves, current and speed profiles, as well as losses and harmonics. However, analytical design has its limitations. While it is useful for a quick assessment of the design, its results are often not precise enough for most current design requirements. Therefore, instead of conducting initial prototyping, a 2D analysis is performed to validate the obtained results and investigate the electromagnetic fields in the motor. This detailed analysis can consider aspects such as nonlinearities, magnetic saturation, and current distribution. It helps refine the analytical calculations, provides insights into the distribution of the electric and magnetic fields, and suggests possible design improvements. This entire process is managed by the HEEDS optimizer, which performs a comprehensive scan of design parameters, topologies, and additional checks, whether analytical or in 2D finite element analysis. Furthermore, evaluations of the impact or sensitivity of variables are conducted, generating studies on the robustness and reliability of the design. In the figure above, we see an example of optimization for a Spoke-IPMSM using the MAGNET software in a 2D simulation coupled with HEEDS. Multifysical Approach As a larger set of parameters is investigated and selected, it becomes necessary to perform more refined 3D studies using advanced simulation software such as MAGNET for three-dimensional electromagnetic simulations. The goal at this stage is to obtain an accurate analysis that considers elements in the third axis of the problem, such as the influence of coil heads on the machine's operation or asymmetric fields. This simulation allows for the validation and improvement of the electric machine model. In addition to electrical analysis, the design of electric machines also involves thermal and fluid dynamics studies (using STAR-CCM+) and structural analysis (using Simcenter 3D). These four areas are strongly interconnected as they affect various material properties, influencing performance and durability. Through three-dimensional multiphysics simulations, a comprehensive analysis of the electric, mechanical, and thermal performance of the electric machine can be performed, ensuring a robust and reliable design. These simulations can even consider the influence of manufacturing details, assembly, and nearby equipment. Next, the design of electric machines must consider the aspects of vibration and acoustics (using Simcenter 3D), which are important limiting factors due to noise or fatigue. Improvements in these areas involve modifications in construction, operational parameters, and materials, affecting all design disciplines. Systemic analysis Finally, it is important to consider the performance of the electric machine in its specific application system (such as a plant, substation, electric vehicle, aircraft, machining center, etc.). At this stage, aspects such as control dynamics, load regimes, duty cycles, and operational transients are evaluated to more realistically reproduce the operating and operating conditions of the equipment. All SIEMENS simulators, such as SPEED, Motorsolve, MAGNET, Simcenter 3D, and STAR-CCM+, generate reduced-order models that can be coupled with simulators or integrators of complex systems, such as Simcenter AMESIM (or Simulink, SystemVision, LabVIEW, VHDL-AMS, SPICE, etc.). Conclusion The digitization of engineering and the integrated workflow with multiphysics simulations have significantly driven the design of electric machines. These advanced approaches allow for the exploration of different topologies, design optimization, validation of analytical results, and overall improvement of motor performance, contributing to more efficient solutions tailored to the specific needs of each application. The integration of these tools in a workflow driven by multidisciplinary optimization enables a deeper and automated exploration of the design space, taking the design of electric machines to a new level of productivity, precision, and robustness.

The use of this innovative technology demonstrates CNPEM's commitment to adopting and developing cutting-edge technologies. Below you will find all the details of this project and how Simcenter MAGNET contributed to its success. Magnetic design for superbend magnets Using simcenter MAGNET to optimize magnetic flux and critical energy in Brazilian particle accelerator CNPEM's Project Sirius is a 4th generation particle accelerator, featuring one of the most advanced synchronous light sources globally. The Sirius superbend plays a crucial role in guiding electrons within the accelerator and enabling light emission. To design the superbend, CNPEM has taken an innovative approach, utilizing permanent magnet technology and optimizing it using Siemens' Simcenter MAGNET software. The result is a magnetic dipole capable of generating stronger magnetic fields, showcasing CNPEM's commitment to adopting and developing cutting-edge technology. Author: Vitor Pereira Soares Title: Technology Development Analyst, CNPEM Introduction Project Sirius is a milestone on Brazilian scientific research, opening new perspectives for the research in areas such as materials science, nanotechnology, physics, and many others. Brazilian Center for Research in Energy and Materials (CNPEM) In the late 1980s, Brazilian researchers built the first synchrotron light source in the southern hemisphere at the Brazilian Synchrotron Light Laboratory (LNLS). This particle accelerator aimed to advance critical technological fields in Brazil. After decades of accumulated knowledge, Project Sirius was developed as an incredibly sophisticated successor to the original accelerator, with worldwide competitiveness. Sirius is expected to facilitate hundreds of academic and industrial research projects annually, involving thousands of researchers, and contribute to solving significant scientific and technological challenges such as developing new drugs and treatments for diseases, creating new fertilizers, cultivating more resilient and adaptable plant species, and innovating technologies for agriculture, renewable energy sources, and many other potential applications with significant economic and social impacts. To construct this fourth-generation particle accelerator, Simcenter MAGNET was employed in the design of the accelerator's magnets and ondulators. Project Sirius Sirius is one of the biggest and most powerful machines of its kind in the world. It has a 3 billion electron-volt energy beam, and its set of magnets, such as the superbend and the delta ondulator, developed with the Simcenter MAGNET software, allows it to provide a hard X-rays in a critical energy of 19keV, allowing more reliable aplication and opening new experimentation horizons. How Sirius works The electron beam is generated by heating of a metallic alloy, exciting the material’s electrons, which are sent to an acceleration structure and to a storage ring. The electrons travel in vacuum tubes at near light speed, and their trajectories are guided by magnetic fields, provided by multipole magnets along the way, such as the superbend dipole; the magnetic net of Sirius is composed of more than a thousand magnets. Sirius’ magnetic net and its magnets composition: dipole, quadrupoles and sextupoles; in the bottom right is the insertion device Synchrotron light Sirius is a machine that accelerate electrons to produce the so called “synchrotron light”, used to study the atomic structures of matter. Synchrotron light is a kind of electromagnetic radiation, composed by frequencies that range from infrared to X-rays. The insertion devices, magnetic structures composed of several alternating dipole fields, such as the Delta Undulators (also using permanent magnetic technology) under development, allows for a million times brighter light than that of its predecessor accelerator (UVX), and expands its reach to the hard X-rays that allow it to penetrate even thicker materials. Benefits of synchrotron light Allows the study of atomic and molecular structures; The synchrotron light’s broad spectrum allows for a wide range of analysis; The high brightness makes for very quick results and material investigation; Allows the project of new materials with specific properties. The Magnetic superbend A new model for Sirius dipoles takes the form of a superbend: a room temperature permanent magnet dipole, able to provide hard X-ray with a critical energy of 19 keV. Siemens software MAGNET was used to design and study the behavior of the magnetic flux in the dipoles. This is the first dipole of this kind to use permanent magnets. The experience with permanent magnets dates back to 2005, with the project of an elliptically polarizing undulator to produce radiation. Through the years the knowledge has been matured and a high field dipole was proposed with the technology, a 2T permanent magnet dipole able to achieve a critical of 12 keV on light production. After some project reviews, the superbend designed with MAGNET expanded that capability to a 3.18 T maximum magnetic field and 19keV synchrotron light production. The higher “brightness” allows the study of denser materials. The superbend project upgrade, besides increasing the light critical energy, increases by a factor of 40 the photon flux at high energies; the enhancement makes the generated light able to penetrate deeper and with a resolution higher than the former dipoles. The C shape eases the access for measurements and maintenance, and the return flux blocks on the side of the magnet can be moved to change the air gap between them. This control gap can be adjusted even after the installation of the magnets in the lattice and will be used in case of demagnetization of the permanent magnet blocks. Magnetic design of Sirius superbend A special NdFeB magnet grade with higher coercivity, coated with NICUNI + Epoxy, with mechanical tolerance of ±0.05 mm for the block’s dimensions and magnetization tolerances of 1° in direction and 0.1% in amplitude, is used in the magnet to allow high precision assembly and integrated field repeatability for all magnets. Magnetic design Several designs were evaluated for the central dipole of the Sirius lattice. Due to the interaction between the magnets, it was decided to use a shared core for three dipoles, forming a single dipole referred to as BC. The BC high field sector is formed by an Iron-Cobalt pole surrounded by NdFeB permanent magnet blocks. Due to the saturation of the pole, it is possible to obtain values of magnetic flux density larger than the remanent magnetization of the blocks. The IronCobalt was chosen for presenting higher saturation magnetization than the carbon steel. In addition, the union of the three dipoles in a single magnet saved space and allowed the placement of permanent magnet blocks in the space between the high and low field sectors to help increasing the flux in the IronCobalt pole. These changes caused the maximum magnetic flux density of the high field sector to increase from 2 T to 3.18 T, which increased the critical energy of the photons from 12 keV to 19 keV. The MAGNET’s addon for design optimization make it possible to use advanced algorithms that can find optimal values for different design variables within the constraints specified. The resource was used to model the permanent magnets’ geometry not only in the superbend’s BC, but also in the other magnets in the system, such as regular dipoles, quadrupoles and the sextupoles. Simcenter MAGNET Suite MAGNET is a powerful electromagnetic field simulation tool for accurately predicting the performance of any component with permanent magnets or coils. Its advanced material modeling takes into account nonlinearities, temperature dependencies, demagnetization of permanent magnets, hysteresis loss, and anisotropic effects. This feature enables the analysis of various effects, such as the demagnetization of permanent magnets, verifying their service life, analyzing frequency-dependent losses in thin parts while reducing solution time, and accounting for all losses for an accurate energy balance. Additionally, MAGNET offers a userfriendly and intuitive interface, allowing users to conduct detailed analysis, optimize their designs, and obtain precise results efficiently Flux density analysis in simcenter MAGNET Magnetic simulations were performed using Simcenter MAGNET software. The simulation investigates the longitudinal profile of the magnetic flux density of the dipole. With the longitudinal gradient obtained with this new version it was possible to reduce the beam emittance by approximately 10%. The table below summarizes the simulation results for the variation of the integrated dipole and quadrupole components of the magnetic field with the shift of the low field and floating poles. As seen, the transverse displacement of the low field poles can be used to adjust the magnet integrated field. Although this displacement also affects the quadrupolar gradient, this component can be further corrected with the rotation of the floating poles. With the closure of the control gap, whose nominal value is of 3.2 mm, it is possible to obtain an increase of .1% in both the integrated dipole and quadrupole field components.

Conclusion The use of permanent magnets in the new accelerator trend of higher fields and small bore radius is a feasible option. Several permanent magnets design were proposed and prototyped and the superbend dipole is installed at the Sirius lattice. The magnetic and mechanical model were carefully planned assuming high challenges in assembly and measurements, as well as the possible effects of temperature variation. Radiation damage was also taken into account, and SmCo was an option, but NdFeB delivers higher field and is being used in insertion devices for a very long time. It was also important to consider some flexibilities in the model to compensate for possible variations in materials permeability, magnetization of the permanent magnets’ blocks, temperature and mechanical errors. The project was a success and Sirius is operating with the 3.2 T superbends for more than two years.
