Abstract:
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 auxiliary 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.

The presentation has received attention, especially attracted was the University of Gent. They perform time consuming CFD calculations with small time step. Capability of FlowVision to march with CFD time step 100 times more than FEA (Abaqus) time step could serve as grounds for collaboration between Capvidia/ÒÅÑÈÑ and University of Gent.

Also, SIMULIA / Abaqus people were interested to compare their solution with ours.
