Run faster, more accurate industrial axial turbomachinery simulations
Making turbomachinery blade passes with polyhedral meshes leads to a comparatively high cell count. This typically manifests itself in increased run times in turbomachinery aerodynamic simulations.
As the main solution, structured meshes were previously introduced in Simcenter STAR-CCM+. This allows for faster response time for axial machines, making the mesh smaller compared to polyhedral and allowing for faster simulation time. The structured mesh also provides high-quality flow-aligned cells in the main blade passage, providing faster simulation convergence and greater solution accuracy.
With Simcenter STAR-CCM+ 2402, the structured mesh capacity of the turbomachine with blade fillet support will be further expanded. These fillets can be on the top or in the center. A seamless user experience is guaranteed with the fillet being automatically detected as part of the blade surface input without any additional input.
Overall, the structured mesh of the turbomachine, together with automatic fillet support, leads to even greater accuracy and faster solution time without any additional effort from the user.
Tackle highly dynamic fluid loads that lead to large solid deformations
For applications where there is a strong bidirectional coupling between a dense fluid and a very flexible structure, convergence and stability of a CFD simulation are very difficult to achieve.
With Simcenter STAR-CCM+ 2402, a set of new features are being introduced that enable exactly this type of complex fluid-structure interaction simulations, where highly dynamic fluid loads lead to large deformations in the solid structure: The new Dynamic stabilization method FSI offers very good control over the simulation with just one adjustable coefficient and is fully compatible with the solid stress load step solver. And with the backward differentiation time integration scheme now also available for the solid stress solver, full kinematic consistency between solid and fluid is now guaranteed even for configurations using 2nd order time integration.
This next-generation fluid-structure interaction (FSI) modeling reduces barriers to dealing with highly dynamic and tightly coupled two-way FSI applications.
Enable applications that involve radiation on participating media
Many applications in the food and beverage, medical and processing industries or in additive manufacturing rely heavily on the volumetric interaction of radiation with a processed material. Therefore, to tackle such scenarios with CFD simulation, an accurate model of radiation absorption and scattering in the presence of a participating media is required.
With the Simcenter STAR-CCM+ 2402, the already existing Surface Photon Monte Carlo SPMC model (which only considers surface-to-surface radiation and ignores the participant/volumetric effect) is being extended to a fully volumetric PMC. Generally, PMC, a statistical method for solving the Radiative Transfer Equation, is considered one of the most accurate solution approaches. With the expansion to volumetric PMC, a combined modeling of volumetric and surface radiation is enabled and therefore an even higher fidelity approach is provided.
This allows for more accurate modeling of complex phenomena such as absorption and scattering of radiation when it interacts with a participating medium. To capture the interaction of radiation with liquids, it can be run in conjunction with Volume Of Fluids (VOF). Thanks to the volume-surface hybrid scheme, users can efficiently use VPMC only in the region where absorption accuracy is required, while maintaining the rest with Surface PMC. This enables impressive speedups of up to 37x compared to a pure Discrete Ordered Method (DOM) solution.
VPMC is further expanding the already rich Simcenter STAR-CCM+ physics offering for radiation modeling (DOM, P1 Spherical Harmonics, Surface-to-Surface, SPMC) with the most comprehensive high-fidelity approach.
Unlock cross-functional synergy for Design Exploration
In a world of increasingly complex products, considering trade-offs between engineering disciplines is of critical importance to maximizing product performance holistically. Therefore, isolated Design Exploration studies not tracked within a single CAE discipline pose the risk of unrealized performance potential.
Simcenter STAR-CCM+ 2402 will introduce a Design Manager integration into Teamcenter Simulation. The integrated solution will allow you to receive real-time updates and notifications about changes in geometry, changes in requirements, parameters, etc., from other engineering teams that may affect your Design Exploration project.
The integrated Design Manager will help your teams accelerate time to market by leveraging Teamcenter's capabilities for Design Exploration: team members can directly access the right data in Teamcenter, ensuring traceability between requirements and results and leveraging a database of centralized project/product information data. The launch of embedded studies from Active Workspace is further democratizing design exploration.
With the resulting improved inter-organizational collaboration, you will be able to realize the full potential through informed optimization of cross-functional product performance.
Perform faster surface preparation for complex geometries
In exterior aerodynamics, CFD engineers need to strive to achieve an efficient distribution of prism layers on the exterior and interior parts of the vehicle. Using existing surface repair tools, splitting low-y+ and high-y+ surfaces can be a tedious process that can take hours or days, depending on user experience and model complexity. The division of part surfaces is also important in any study when, for example, the reporting of a quantity at a specific limit or the assignment of boundary conditions is desired.
The Simcenter STAR-CCM+ 2402 will incorporate an interactive classification tool for surface repair that speeds up the division of part surfaces. The feature comes with an intuitive user interface and state-of-the-art algorithms that enable fast and efficient classification and save time. The tool can be applied to individual parts or to a set of parts that can have different tiling levels.
The sorting process is fast and faces can be sorted in seconds. The tool also allows you to record a macro, for even faster classification of different design variants. Therefore, for outdoor aerial simulations, valuable surface preparation time as well as mesh count can be saved. This also leads to reduced solver execution time with minimal differences in drag count.
Go faster with access to a wider range of hardware for native GPU acceleration
The benefits of GPU-enabled acceleration of CFD simulations are, however, unquestionable. Significantly lower cost per simulation for the same number of designs, massively reduced power consumption, and the ability to replace thousands of CPU cores with a single GPU node. However, until now, GPU-enabled acceleration in Simcenter STAR-CCM+ has been tied to a single GPU hardware vendor, limiting your options.
Now, calculations in Simcenter STAR-CCM+ 2402 can be performed on both AMD and NVIDIA GPUs. In this release, you can now take advantage of AMD Instinct™ 200 series GPUs (MI210, MI250, MI250X), with unchanged consistency in results regardless of your chosen hardware, whether CPU or GPU. This offers a wider selection of hardware, easier access to GPU-accelerated CFD, and ultimately more flexibility to obtain CFD results in the most efficient way possible.
Run CHT and multi-timescale simulations more efficiently with native GPU solvers
As described above, GPU-accelerated CFD simulation has a long list of benefits, including the potential to run your simulations in a cost-effective and energy-efficient manner. Consequently, benchmarks over the last few release cycles have proven the excellent performance of Simcenter STAR-CCM+ on GPUs. And so, it is of fundamental importance to expand the ability to leverage GPUs for more models and, consequently, more applications.
Simcenter STAR-CCM+ 2402 therefore follows the portability of solvers and resources to make them equally available for native GPU and CPU simulations. The new version offers GPU-native implicit and explicit fluid-solid and/or solid-solid mapped contact interfaces and a GPU-native multipart solid material properties model.
Together, these improvements make it possible to run conjugate heat transfer (CHT), vehicle thermal management (VTM), and other multi-timescale simulations on GPUs with all the associated benefits. CPU-equivalent solutions are guaranteed by maintaining a unified code base.
Significantly accelerate multispecies coupled flow simulations
Applications involving reactive flows can be found in many sectors. And although CFD simulation can cover all aspects related to chemical reactions with a high level of accuracy, it comes at a cost. Typically, fully coupled flow, energy and species simulations can be very computationally demanding.
Therefore, in Simcenter STAR-CCM+ 2402, you now have the possibility to use the Segregated Species solver in conjunction with the Coupled Flow and Energy solver, as an alternative to a fully coupled Flow-Energy-Species approach. Solving species transport in a segregated manner reduces the computational time of the entire system, with large speedup benefits of up to x10 depending on the use case or – more precisely – the number of species involved.
Note that while the Coupled Flow/Energy with Segregated Species approach can provide a significant speedup for multi-species simulations, certain more complex reactive cases are expected to require a full Flow/Coupled Energy and Coupled Species approach.
Smoothed Particle Hydrodynamics (SPH) Integration in Simcenter STAR-CCM+ 2402
ASmooth-Particle Hydrodynamics (SPH) technology is a very powerful and fast alternative method for modeling complex transient flows with highly dynamic free surface flows, including jets and splashes. However, standalone tools for SPH and mesh-based CFD force users and engineering teams to choose the tool a priori and eventually work across several different tools depending on the exact simulation requirements.
In Simcenter STAR-CCM+ 2402, the first version of the SPH solver, which is fully integrated into the platform, was released, allowing you to run SPH and mesh-based simulations from the same tool. Because SPH does not require volume meshing, it allows you to quickly handle complex body movements, even with contact and complex geometries. By integrating with Simcenter STAR-CCM+ you will immediately benefit from the power of Simcenter STAR-CCM+ as a CFD simulation platform: Integrated end-to-end workflow automation, advanced preprocessing with a built-in CAD tool and external CAD connectivity seamless, powerful data analysis and design space exploration integrated with Design Manager.
Ultimately, the integration allows you to run multiple types of multiphase applications in a single environment, expanding your options beyond established finite volume methods like VOF or MMP to a fast, meshless SPH method. All this without the need to learn and maintain an additional CFD software tool. In this first version, the lubrication of the powertrain using an oil bath was prioritized. Please note that to be able to run the SPH solver, customers will need an additional license.
These are just a few highlights of the Simcenter STAR-CCM+ 2402. These capabilities will enable you to design better products faster than ever before, turning today's engineering complexity into a competitive advantage.
