Faster high fidelity simulations through GPGPU acceleration
GPU-enabled acceleration of high-fidelity CFD models in the Simcenter STAR-CCM+ 2210 offers significant potential for acceleration and power savings. Vehicles Shown: Aerodynamics at DrivAer TU Munich, DES and Aeroacoustics at 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 deliver calculation speedups, energy and cost savings.
You can now run high-fidelity Large Eddy Simulations (LES) simulations on GPUs, further extending the benefits of the GPU to high-fidelity aerodynamics. As for RANS and DES, aerodynamic benchmarks continue to show significant speed increases, potential energy and cost savings for high fidelity turbulence modeling.
Also, in version 2210, cutting-edge acoustic wave models became compatible with GPU hardware . With the portability of the Lighthill Wave model and the Perturbed Convective Wave model, you will experience fast turnaround times from high fidelity aeroacoustic simulations to applications such as side mirrors or HVAC ductwork.
The Simcenter STAR-CCM+ 2210 also enables GPU acceleration of the segregated power solver with the ideal gas equation of state. This will significantly speed up your thermal analysis simulations, such as transient cooling DES analysis on the trailing edge of a turbine blade.
With these enhancements, we continue to enable you to model the complexity of today's products while working faster. Thus ensuring consistent results between GPU and CPU based calculations.
Model the complexity
Improved physical realism and insights for DEM simulations
Flexible fibers with velocity dampening in the Simcneter STAR-CCM+ 2210 increase the fidelity and accuracy of your DEM simulations
The DEM discrete element method offers enormous potential for simulating applications in heavy equipment and the process industry.
With the introduction of meshfree DEM in Simcenter STAR-CCM+, we begin our efforts to significantly speed up bulk material handling simulations in situations where aerodynamic forces are negligible. Flexible fibers for a mesh-based DEM workflow in version 2021.3 became compatible with non-meshed DEM in version 2022.1, followed by the addition of fiber breaking features in version 2206. All of these updates contribute to improved physical fidelity when modeling complex processes such as cutting or harvesting with agricultural equipment.
With the Simcenter STAR-CCM+ 2210, we continue these enhancements by introducing velocity damping physics at the location of links between fiber segments. The simulation of flexible fibers with damping is more accurate and stable, even when running at a higher DEM timestep . Previously, oscillations of strained fibers continued indefinitely if no energy-dissipating interactions with fluid or other fibers, or geometry were taking place.
To further increase your DEM productivity, Simcenter STAR-CCM+ offers quick and easy setup of DEM Moment and DEM Force reports. Now you can easily monitor relevant quantitative data such as the integrated torque on the rotating blades caused by particle structure interaction. Time-averaged force or moment on each face of a part allows you to explore particle-induced charge distributions.
Together, these enhancements allow for faster simulations of complex bulk material physics to explore the possibilities for better agricultural and process equipment.
Increased flexibility for liquid fuel spray separation modeling
User-defined Lagrangian fragmentation modeling will give you more flexibility to model complex fragmentation scenarios, as in this afterburner of a jet engine.
Useful in many applications, for some others, classic secondary separation models (such as SSD, TAB, Reitz-Diwakar, KHRT) may not always provide acceptable accuracy for droplet size distribution. Although 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 separation model for Lagrangian multiphase to allow you to implement any existing separation model in the literature with maximum flexibility. The implemented solution allows you to specify an arbitrary number of picking results and then enter the picking map using the field function or table input method. The separation map specifies the conditions for each separation result.
To simulate combustors in gas turbines or breakdown in sprays generated by pre-shot air jet atomizers used in aircraft engines, it is difficult to obtain sufficiently accurate predictions with standard breakdown models. The new user coding option offers complete flexibility to implement any model tailored to the application, such as Madabhushi separation for cross flow fuel jets.
Robust and accurate highly dynamic fluid-structure interaction simulations
With the Generalized-α scheme and a low power dissipation, it is now possible to run this challenging FSI benchmark from 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 the context of fluid-structure interaction (FSI).
With Simcenter STAR-CCM+ 2210, we introduced Generalized-α time integration, which increases the accuracy of FSI simulations, making it possible to solve more models with 2nd order time integration. This is possible due to the controlled power dissipation in the scheme, increasing the robustness. Unlike the previously available Newmark scheme, Generalized-α will always be 2nd order accurate, regardless of the choice of integration coefficients. Three preset settings for specifying the amount of dissipation desired make it easy for a novice user to take advantage of the highest precision scheme, while the user-specified method gives the freedom for an expert to define all the coefficients.
The new feature will allow you to no longer compromise the fidelity and accuracy of the results, offering greater stability for simulations of highly complex and dynamic fluid-structure interactions.

Smoother fluid-solid interface with built-in AMR ( Adaptive Mesh Refinement ) 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 for accelerating simulations while ensuring accuracy and stability. Flow-based topology optimization allows you to generate completely new and innovative designs.
In Simcenter STAR-CCM+ 2210, we leverage AMR to better resolve the fluid-solid interface that represents the new shaping design in the domain of topology optimization. Two cutting-edge simulation technologies are brought together while minimizing effort by introducing a new built-in AMR criterion for topology optimization called
Topology physics mesh adaptation. Built-in AMR criteria reduces the chance of error and increases ease of use compared to the previous option of a user-defined template. The use of AMR in the topology optimization process generates better resolution of the fluid/solid interface, improving accuracy and providing smoother surfaces as a starting point for subsequent additive manufacturing steps.
