In the Partner exhibition we will demonstrate FlowVision simulations (parallel version with direct Abaqus interface) illustrating our approach to multi-physics realistic CFD simulation. Do not miss this opportunity to meet our CFD experts. At AUC 2008 Capvidia will go with "Drop-Test FSI simulation with Abaqus and FlowVision based on the direct 2-way coupling approach". The paper presents a numerical simulation of the drop test in a still water for the multi-component box structure. The complexity of the problem is in the strong fluid-structure interaction (FSI) between the box and the water free surface.
The numerical simulation of the drop test is performed with two software tools: Abaqus and FlowVision through the direct coupling interface, which manipulates, on the Abaqus side the Lagrangian finite-element mesh and on the FlowVision side the Eulerian finite-volume mesh with subgrid geometry resolution.
The novel approach is that there are no auxilliary structure models (or 3rd party software) integrated in the applied software solution: the finite-element mesh is defined from the Cartesian CFD finite-volume mesh and all the relationships between the CFD mesh cells and the outside FE faces are fully preserved. Each mesh node displacement is directly transferred between FlowVision and Abaqus, thus avoiding any additional interpolation.
