STAR-CCM+ has a direct link to Abaqus FEA through co-simulation, delivering fully coupled, two-way, fluid-structure interaction. STAR-CCM+ co-simulation gives users the flexibility to choose between explicit and impicit coupling, depending on the application. The implicit coupling approach is particularly beneficial for applications in the Life Sciences Industry because of the complex cross-coupling between the biological fluid and the highly flexible tissue.
In addition to direct co-simulation, STAR-CCM+ also enables FSI computations through importing/exporting meshes in other native formats (e.g. Nastran/Ansys) as it leverages the power of JAVA and gives users the ability to customize every step of the work flow.
The built-in mapping implemented in STAR-CCM+ is robust and accurate and efficiently handles non-conformal meshes with no need for writing scripts or input files.A multi-quadratic morphing capability robustly and smoothly moves the meshes (of any topology) based on the deformation it receives from the structures solver. The resulting mesh conforms to the shape of the deflected structure and the redistribution of the mesh vertices nicely preserves the quality of the original mesh. In addition to mesh morphing, STAR-CCM+ also has an overset mesh capability.
Using the FSI capability in conjuction with STAR-CCM+'s unrivaled meshing technologies, high-fidelity multi-physics and intuitive user environment results in an FSI capability that is flexible, accurate, robust and efficient.
