“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 sub grid geometry resolution.

Crash Prediction for Marine Engine Systems Presented at the 2008 Abaqus Users’ Conference

Mercury Marine outboards, engines, and drives are designed to withstand indoor impact testing (called “logstrike”) that simulates a collision with an underwater object. This test is comprised of an outboard or sterndrive device mounted on a mock boat that collides with a simulated log.
