According to Jean-Claude Ercolanelli, CD-adapco’s VP Product Management, the arrival of STAR-CCM+ V3.06 represents a true paradigm shift in the simulation of multi-field and multi-domain problems:
”Everyone appreciates that most practical problems involving fluid dynamics are in some way also related to the interaction between fluids and one or more solid bodies. In the past, Fluid Structure Interaction (FSI) normally required manual sequential coupling between CFD and structural analysis software”, says Ercolanelli. “The implementation of finite volume solid stress modeling within STAR-CCM+ has changed this situation, providing users with the ability to automatically solve the physics of both fluid and solid domains simultaneously, resulting in a complete simulation of Fluid Structure Interaction (FSI) using a single computational model”.
Mesh Morphing and Multi-body Dynamic Fluid Body Interaction
This latest version of STAR-CCM+ extends the recently introduced DFBI modeling capabilities by introducing the ability to simulate the movement of solid bodies using either embedded motion or mesh morphing. By enclosing the body to be studied in a spherical or cylindrical sub-domain, the embedded motion technique allows the simulation of extreme levels of rotation such as lifeboats falling into water or shipping containers slamming into the ocean. While the sub-domain is free to rotate without limitation, the rotation and translation of the outer fluid domain may be limited; ensuring robustness of solution without having to resort to time and resource consuming re-meshing techniques.
For more complex movements and situations involving multiple bodies, STAR-CCM+ now has the ability to “morph” the volume mesh either prescribed by the user or automatically when invoked by the DFBI model. By deforming the mesh around an object, without the need for remeshing, the morphing model can be used to simplify many moving mesh simulations including fluid and rigid body-interaction as well as design optimization studies.
Improved productivity and CAD/CAE integration
STAR-CCM+ V3.06 also includes a wide range of enhancements aimed at improving the quality of your simulation results while increasing your productivity:
- Native CAD readers: get the latest geometry configurations from Designers without translation or file duplication
- Projection back to CAD after remeshing or wrapping: high quality meshes can now be created on curved surfaces, such as those at the leading edge of an aerofoil.
