In computations of fluid flow with structural interactions (FSI) or fluid flow with moving boundaries, it is necessary to update the mesh topology when the mesh is no longer valid due to node movement. This is accomplished in ADINA using a mesh adaptation-repair procedure based on the Delaunay meshing methodology. This procedure performs the following tasks:
