FINITE-ELEMENT SOLUTION STRATEGIES FOR LARGE-SCALE FLOW SIMULATIONS

Large-scale flow simulation strategies involving implicit finite eleme nt formulations are described in the context of incompressible flows. The stabilized space-time formulation for problems involving moving bo undaries and interfaces is presented, followed by a discussion of mesh moving schemes. The methods of solution of large linear systems of eq uations are reviewed, and an implementation of the entire finite eleme nt code, permitting the use of totally unstructured meshes, on a massi vely parallel supercomputer is considered. As an example, this methodo logy is applied to a flow problem involving three-dimensional simulati on of liquid sloshing in a tank subjected to vertical vibrations.
