A new release of Simcenter STAR-CCM+ 2502 is available.

The latest Simcenter STAR-CCM+ 2502 release introduces enhancements to improve simulation efficiency, accuracy, and ease of use. With the new Virtual Body approach  and Boundary Interface Caching Strategy this update delivers powerful tools that streamline workflows and enhance simulation capabilities.

Virtual Body: A Smarter Way to Simulate Moving Objects

Many industrial applications—such as paint dipping and bottle filling—involve solid bodies that affect fluid motion. Traditionally, an overset meshing approach was used, combining a background mesh with a body-fitted mesh to capture fluid movement with high accuracy. While this method provided flexibility, it required two separate meshes, making the setup more complex.

With Simcenter STAR-CCM+ 2502, the new Virtual Body feature eliminates the need for multiple meshes. This approach also ensures greater solution stability in scenarios with tight gaps, leading to more precise and reliable simulations.  the Virtual Body method offers a simplified setup process, which is also a more scalable and cost-effective alternative to traditional methods.

Enhanced Sliding Mesh Performance with Boundary Interface Caching

Sliding mesh simulations play a crucial role in turbomachinery, rotating equipment, and other moving part applications. However, they can be computationally demanding, requiring the interface intersection to be repeated at each time step.

With Simcenter STAR-CCM+ 2502, the Boundary Interface Caching Strategy significantly reduces simulation time by caching interface data and reusing it for subsequent time steps. This improvement accelerates sliding mesh simulations, and making the solver process more efficient and ensuring smoother overall performance.

Stages Feature: Simplifying Multi-Stage Simulations

Complex simulations often involve multiple physical phenomena or operational phases, making setup time-consuming and script-heavy.

The new Stages feature in Simcenter STAR-CCM+ 2502 simplifies this process with an intuitive interface for defining and managing different simulation stages. Instead of relying on manual scripting, engineers can now transition effortlessly between operational conditions, significantly reducing setup time. This allows them to focus more on analysis and less on configuration, making multi-stage simulations more efficient than ever before.
