Accelerate your CFD simulations by over 30% with the SIMPLEC scheme. Document, share and review detailed model information in CFD software .


Simcenter STAR-CCM+ 2302 comes with several new features that let you go faster while modeling complexity.


 

Battery thermal runaway setup in minutes

CFD simulation of battery thermal runaway. With a dedicated workflow, configuring complex heat release physics is significantly faster and easier with the Simcenter STAR-CCM+ 2302


With the rapid growth of electric vehicles circulating on the roads, new safety rules have been implemented at the national and international level, with new UN safety rules on the use of lithium-ion batteries.


This legislation forces major battery manufacturers and users to perform a number of expensive and time-consuming tests to obtain certifications. This leads to an increasing demand for simulation to reduce the cost of testing and make security design cost effective.


In Simcenter STAR-CCM+ 2302 , a dedicated workflow was released to accelerate the setup time of thermal runaway propagation simulations for batteries from hours to minutes. Thanks to a focused workflow, you can now handle large batches of hundreds or thousands of cells with ease while maintaining high modeling fidelity. The workflow supports direct simulation of exothermic heat release from “failed” cells with an empirical model and is accessible as part of the Simcenter STAR-CCM+ Batteries add-on .


Thanks to its powerful multiphysics capabilities and new dedicated workflow, Simcenter STAR-CCM+ is perfectly suited to study the propagation of uncontrolled thermal events in complex packaging geometry. Simcenter STAR-CCM+ provides a comprehensive solution to better understand this dangerous security event and helps design packages and mitigation measures, thereby reducing the need for costly testing.


 

Easy and accurate modeling of motion with overset meshes

With the Simcenter STAR-CCM+ 2302 , you can run cases more reliably with small gaps and motion, thanks to the refined overset region that matches the refinement level of the background region.


Warehouse separation, valves, dip coating and many other applications involve moving bodies, with small spaces in conjunction with complex fluid dynamics. To simulate such complex CFD applications, overset mesh technology along with Adaptive Mesh Refinement (AMR) has become a key technology.


With the Simcenter STAR-CCM+ 2302 , we make it easy to run these cases by automatically refining the overlay region to match the refinement level of the background region. Small gap scenarios will immediately benefit from the new feature, ensuring valid meshes and guaranteed convergence with no additional user effort.


 

Model new applications involving the drying of wet solid materials

Simulating electrode paste drying in an industrial convection oven (part of the battery manufacturing process) using DEM with liquid evaporation is now possible thanks to the extension of evaporation models to DEM phases


Many applications in the chemical processing, mining, steel, food and battery manufacturing industries involve drying wet solids. CFD simulation of such systems requires accurate prediction of particle motion and related phase change phenomena.


In Simcenter STAR-CCM+ 2022.1 , therefore, we introduced the Liquid-Solid-Gas material for non-DEM Lagrangian particles, allowing to apply evaporation modeling for droplets containing solid materials. This functionality is, for example, successfully used to simulate milk droplets in spray drying.


With the Simcenter STAR-CCM+ 2302 , we have extended the capabilities of discrete element method (DEM) particles, allowing you to apply evaporation models to DEM phases. This allows you to model new applications involving the drying of solid materials where DEM is the particle dynamics method of choice, allowing evaporation of liquid components into DEM particles.


Thanks to the new feature, you can accurately simulate drying processes in direct convection based dryers such as drum dryers, spray dryers, fluidized bed dryers or indirect conduction based dryers using the discrete element method for the phase wet solid.


 

Best performance for price with ARM support

With the Simcenter STAR-CCM+ 2302 , we enable you to run bigger, faster CFD simulations for less cost and energy using Advanced Reduced Instruction Set Computer Machines (ARM) CPU technology.


Simulation has become a critical factor in time- and resource-efficient product development. And while CFD simulation consumes significantly less resources than the corresponding physical test, to remain competitive, companies must go one step further. With the ever-increasing volume of simulation-based product designs, to gain a competitive advantage, you must optimize the energy consumption and costs associated with these high-fidelity simulations. Ultimately, a sustainable, cost-effective and energy-efficient digital twin is a differentiating factor and competitive advantage in virtual product development.


With the Simcenter STAR-CCM+ 2302 , we enable you to run bigger, faster CFD simulations for less cost and energy using Advanced Reduced Instruction Set Computer Machines (ARM) CPU technology .


The technology is currently supported on Linux and is available through different cloud providers such as AWS EC2 instances or the Fugaku supercomputer provided by Fujitsu in Japan.


With ARM support, we've added another option to run your CFD simulation on an increasingly heterogeneous hardware architecture landscape . Whether GPU or CPU, local or cloud, ARM or conventional CPUs, Simcenter STAR-CCM+ offers a variety of options to maximize your throughput.


 

Bigger and faster simulations on GPUs

Simcenter STAR-CCM+ 2302 comes with a reduced memory overhead on GPUs, allowing you to fit larger models onto a single GPU with immediate performance benefits.


Typically, the size of simulation that can be run on GPUs is limited by the available memory (RAM) of a GPU card. Therefore, by reducing the memory footprint of a given simulation, you can fit larger meshes onto a single GPU. This is particularly useful as the most efficient GPU performance is seen when cards are "maximum", which means fitting as many cells as possible onto a single card.

To maximize benefits, the Simcenter STAR-CCM+ 2302 comes with reduced memory overhead and improved performance through more efficient use of AmgX, as well as updates to CUDA, the NVIDIA API. In addition to the existing performance benefits of previous GPUs, these enhancements result in up to 40% memory reduction as well as up to 10% runtime performance improvements. As an example, a single NVIDIA A100 with 80GB of memory can now accommodate around 60 million cells trimmed in mixed precision.


With these enhancements, we continue our strategy to support fast and efficient CFD simulation on GPUs while maintaining consistency with CPU-based results.


 

Up to 40% faster simulations at no cost

In Simcenter STAR-CCM+ 2302 , we introduced a new implicit unstable scheme for the segregated flow solver : the SIMPLE-Consistent one, called SIMPLEC. SIMPLEC allows significant speedup for simulating transient flows while still achieving the same accuracy as SIMPLE.


Adding to the benefits of new hardware and massive scalability for high-performance computing, accelerating your CFD simulation through more efficient solving techniques remains the most cost-effective way to go faster.


In Simcenter STAR-CCM+ 2302 , we introduce a new implicit unstable scheme for the segregated flow solver : the SIMPLE-Consistent one, called SIMPLEC.


SIMPLEC allows a significant speedup for simulating transient flows due to deeper convergence of the solution within the time interval. Thanks to SIMPLEC, you can achieve the same accuracy as SIMPLE with a reduced number of internal iterations per time step. When using convergence-based stopping criteria for inner iterations, there is no need for adjustment when applying the new SIMPLEC scheme.


For applications ranging from exterior vehicle aerodynamics through side mirror and HVAC aeroacoustics to aircraft wing icing, SIMPLEC results in a reduction of up to nearly 30% of total turnaround time. All this ensuring consistency of results between the SIMPLE and SIMPLEC approaches. And at no additional cost.

 
Accelerate multiphase simulations without losing fidelity

The potential of Implicit Multi-Step to speed up MMP-LSI simulations is illustrated by this gearbox lubrication example. When using 16 substeps, the acceleration is approaching 4x.


In applications such as gearbox splatter droplets can break down into smaller and smaller sizes until you can no longer model the very small droplets as Lagrangian particles. At the same time, you still need to model the free surface of the bulk liquid. For such applications, multiphase mixing modeling with large scale interface (MMP-LSI) has become the method of choice. In general, MMP-LSI is relevant anywhere you have Fluid Volume (VOF), but that would be too expensive and a mixture is present.


But like VOF, MMP-LSI has a comparatively high cost if you cannot decouple the choice of flow time interval from that required to fulfill the small time interval required for the volume fraction due to numerical Courant constraints. (CFL). To overcome this challenge, we previously implemented Implicit Multi-Step for VOF , where simulations were typically accelerated by 3-4x, and in some cases by up to an order of magnitude.


In Simcenter STAR-CCM+ 2302 we are adding the same feature for MMP-LSI. Implicit Multi -Step allows a larger time range to be used for the flow (excluding the volume fraction) by sub-steps the volume fraction multiple times within the flow time range. This separates the choice of flow time interval from that required for the volume fraction due to CFL restrictions.

 

Easily understand a design space using contour plots


With Simcenter STAR-CCM+ 2302 , you can now quickly and easily generate performance maps with two independent variables and one dependent variable.


For many applications, eg turbomachinery, CFD is a very powerful and cost-effective tool to generate performance maps through automated scans. These maps will give you immediate information about how a dependent variable is performing as a function of multiple independent variables.


With Simcenter STAR-CCM+ 2302 , you can now quickly and easily generate performance maps with two independent variables and one dependent variable. This will allow you to add a layer of information to the standard XY chart via contour charts. Interpolation is used to draw the contour lines and the display of external data, say from experiments, is supported via tables.


Thanks to the new feature, you will get information about a complete performance map with isolines in just a few clicks.

 

Integrated access to simulation information

In Simcenter STAR-CCM+ 2302 , we introduce the simulation guide. The simulation guide allows you to store all relevant information within the simulation file, significantly increasing your productivity. Combined with the simulation model functionality, it will take your productivity to new heights.


In today's complex engineering world, efficient collaboration and sharing of relevant information between engineers is more important than ever. For simulation engineers, wasting their time looking for disconnected external resources to get the latest simulation setup documentation or usage instructions for model simulations is a huge productivity burden. For CFD simulations, this entails traceable data and workflow management and the ability to work in an integrated environment, allowing you to access all relevant simulation information quickly and directly.


In Simcenter STAR-CCM+ 2302 , we introduce the Simulation Guide. The Simulation Guide allows you to store all relevant information within the simulation file. Having notes or instructions directly in the simulation file increases your productivity as you spend less time looking for information. With a built-in editor, you can add all relevant metadata exactly where it's needed: inside the simulation file. The editor allows you to write text, format it, add images, create tables. As a result, the simulation guide allows you to share, update and review information relevant to the simulation. It helps your team collaborate and build collective knowledge.


Along with the model simulation file introduced in Simcenter STAR-CCM+ 2022.1 , the Simulation Guide will take your productivity to new heights: simulation model authors can leave detailed instructions exactly where needed, while model users can now quickly understand setup steps, leveraging streamlined workflow instructions while staying within the CFD environment.

 

These are just a few highlights of the Simcenter STAR-CCM+ 2302 . These capabilities will enable you to design better products faster than ever before, turning today's engineering complexity into a competitive advantage.
