Go faster

Faster high-fidelity simulations through GPGPU acceleration

GPU-enabled acceleration of high-fidelity CFD models in Simcenter STAR-CCM+ 2210 offers significant speed-up and energy-saving potential. Vehicles shown: Aerodynamics on DrivAer TU Munich, DES and aeroacoustics on AeroSUV, FKFS Stuttgart

Aerodynamics, aeroacoustics and high-fidelity heat transfer are all resource-intensive challenges for Computational Fluid Dynamics (CFD). At the same time, GPU-accelerated CFD simulations continuously prove to offer significant calculation speedups, energy, and cost savings.

With Simcenter STAR-CCM+ 2210, we continue our porting efforts of solvers to leverage GPU-enabled acceleration. You can now run high-fidelity Large Eddy Simulations (LES) on GPUs further extending GPU benefits for high-fidelity aerodynamics. Like for RANS and DES aerodynamic benchmarks continue to show significant speedups, energy and cost-saving potentials for high-fidelity turbulence modeling.

Moreover, in version 2210 cutting-edge acoustic wave models have been made compatible with GPU hardware. ​With the porting of the Lighthill Wave model and the Perturbed Convective Wave model, you will experience rapid turnaround times of high-fidelity aeroacoustics simulations for applications such as side mirrors or HVAC ducts.

Simcenter STAR-CCM+ 2210 also enables the GPU acceleration of the Segregated Energy solver with the Ideal Gas equation of state. This will significantly speed up your thermal analysis simulations, like DES transient cooling analysis at a turbine blade trailing edge.

​With those enhancements, we continue to enable you model the complexity of today’s products while going faster. Thereby ensuring consistent results between GPU and CPU-based calculations.

Model the complexity

Improved physical realism and insights for DEM simulations

Flexible fibres with velocity damping in Simcneter STAR-CCM+ 2210 increase the fidelity and accuracy of your DEM simulations

The discrete element method DEM offers huge potential for the simulation of applications in the heavy equipment and the process industry.

With the introduction of meshfree DEM in Simcenter STAR-CCM+, we started our efforts to significantly speed up bulk material handlings simulations, in situations where aerodynamic forces are negligible. Flexible fibers for a mesh-based DEM workflow in version 2021.3 became compatible with meshfree DEM in version 2022.1, followed by the addition of fiber breakage capabilities in version 2206. All these updates contribute to improving the physical fidelity when modeling complex processes, like chopping or harvesting using agricultural equipment.

With Simcenter STAR-CCM+ 2210, we continue those enhancements by introducing the velocity-damping physics at the location of bonds between fiber segments. Flexible fibers​ simulation with damping are more accurate and stable, including when running at larger DEM timestep. ​ Previously the oscillations of the deformed fibers continue indefinitely if no energy dissipative interactions with fluid or other fibers, or geometry are taking place.

To further boost your productivity with DEM, Simcenter STAR-CCM+ offers the quick and easy setup of DEM Moment and DEM Force reports. You can now easily monitor relevant quantitative data like the integrated torque on rotating blades caused by particle structure interaction. The time-averaged force or moment on each face of a part enables you​ to explore particle-induced load distributions.

Together those enhancements allow for faster simulations of complex physics of bulk materials to explore the possibilities for better agricultural and process equipment.

Greater flexibility for liquid fuel spray break-up modeling

User-defined Lagrangian break-up modeling will give you more flexibility to model complex break-up scenarios like in this afterburner of a jet engine

Useful in many applications, for some others, classical secondary breakup models (like SSD, TAB, Reitz-Diwakar, KHRT) may not always provide acceptable accuracy for the size distribution of droplets. While a high-fidelity hybrid multiphase approach offers an accurate alternative it is not always feasible due to simulation effort constraints.

In Simcenter STAR-CCM+ 2210, we therefore introduce the user-defined breakup model for Lagrangian multiphase to allow you to implement any existing breakup model in literature with maximum flexibility. The implemented solution allows you to specify an arbitrary number of the breakup outcomes and then input the breakup map using field function or table input method. The breakup map specifies the conditions for each breakup outcome.

For simulating combustors in gas turbines or breakup in sprays generated by pre-filming air blast atomizers used in aero-engines, it is difficult to get sufficiently accurate predictions with standard break-up models. The new user coding option offers you full flexibility to implement any application-tailored model like e.g. the Madabhushi breakup for fuel jets in cross-flow.

Robust and accurate highly dynamic Fluid-Structure Interaction Simulations

With the Generalized-α scheme and a low energy dissipation it is now possible to run this challenging FSI benchmark by Lienhart and Gomes with 2nd order time integration leading to accurate predictions

First-order time integration schemes are known to dissipate a significant amount of energy. This can lead to inaccurate results, especially for applications involving impact events such as a bottle drop test. At the same time a small and well-controlled amount of energy dissipation often significantly improves the robustness of the simulation, especially in Fluid-Structure Interaction (FSI) context.

With Simcenter STAR-CCM+ 2210 we introduce the Generalized-α time integration which increases the accuracy of FSI simulations by making it possible to solve more models with 2nd order time integration. This is possible due to controlled energy dissipation in the scheme which increases robustness. Opposed to the previously available Newmark scheme Generalized-α will always be 2nd order accurate, independent of the choice of the integration coefficients. Three predefined settings to specify the amount of desired dissipation make it easy for a novice user to leverage the higher accuracy scheme, while the User Specified method offers the freedom to an expert to define all coefficients.​

​​The new capability will allow you to no longer compromise on results fidelity and accuracy while offering increased stability for highly complex and dynamic Fluid-Structure Interactions simulations. 

Simcenter STAR-CCM+ 2210_Topology Optimization

Explore the possibilities

Smoother fluid-solid interface with built-in AMR ​for Topology Optimization

Combine Adaptive Mesh Refinement AMR with Adjoint-based Topology Optimization for higher fidelity fluid-solid interface representations

Adaptive Mesh refinement is a key technology to speed-up simulations while ensuring accuracy and stability. Flow-based topology optimization allows you to generate completely novel and innovative designs.

In Simcenter STAR-CCM+ 2210 we leverage AMR to better resolve the fluid-solid interface which represents the new forming design in the topology optimization domain. Two cutting-edge simulation technologies are put together whilst the effort is minimized by the introduction of a new built-in AMR criterion for topology optimization called Topology Physics Mesh Adaption. The in-built AMR criterion reduces the chance for error and enhances ease of use compared to the previous option of a user-defined model. The use of AMR in the topology optimization process generates a better resolution of the fluid/solid interface improving the accuracy and offering smoother surfaces as a starting point for subsequent additive manufacturing steps.
