Simcenter STAR-CCM+ Improves Simulation Time, Accuracy

Siemens Digital Industries Software announced the latest release of Simcenter™ STAR-CCM+ software, part of the Simcenter portfolio of simulation and test solutions. According to Siemens, the latest release of Simcenter STAR-CCM+ includes enhancements to improve simulation time and accuracy as well as enhance collaboration, giving customers a comprehensive digital twin to help drive predictive simulations. In this release, Siemens has also introduced a new parallel polyhedral mesher for faster, more effective meshing, as well as a model-driven adaptive mesh refinement (AMR) solution. The latest release includes automatic coupled solver control for reduced set-up time, and a collaborative virtual reality (VR) feature in the CFD code to improve collaboration.

The fully-rewritten parallel polyhedral mesher uses parallel performance to build meshes up to 30 times faster than in serial, providing a consistent mesh regardless of the cores used and a more effective mesh distribution with the same accuracy and robustness, the company says. New adaptive mesh refinement (AMR) technology intelligently refines the mesh based on the physics. This can lead to less user interaction as well as computational overhead and reduces overall mesh size.

Automatic solver controls improve the ease-of-use and robustness of the coupled solver. Siemens says that this delivers faster convergence to solution giving users additional speedup for all flow regimes straight out of the box.

Collaborative VR in Simcenter STAR-CCM+ allows teams to interact in the same immersive virtual environment in real time. Multiple VR clients can now be connected and synchronized to the same simulation, with avatars showing the location of other users and providing the ability to tether users to get the same experience.
