FlowVision-HPC combined with Abaqus offers unique capabilities for solving heavily coupled fluid-structure-interaction problems. The implementation is based on the SGGR (Sub-Grid-Geometry-resolution) method used in FlowVision for grid generation. The SGGR method provides natural link between CFD grid and FEA mesh.

The process is fully automatic and can involve geometry of arbitrary complexity. The MPM (Multi-Physics-Manager) controls both FlowVision and ABAQUS during the simulation process. The data is exchanged using direct coupling providing optimal data transfer rates and accurate data exchange. Direct coupling allows using parallel processing both on fluid (FlowVision) as structure (Abaqus) side resulting in realistic simulations times. Most complex FSI problems can be solved over the night (e.g. hydroplaning of automotive tire). Simple set-up with and possibility to use not matched meshes (fluid-structure) allows solving the most complex fluid structure interaction problems involving highly deformable and moving structures.
