Large-Scale Fluid-Structure Interaction Simulations Using Parallel Computers

A methodology to simulate large-scale fluid-structure interaction prob­lems on parallel machines has been developed. Particular emphasis was placed on shock-structure interaction problems. For the fluid, a high-resolution FEM-FCT solver based on unstructured, moving, body fitted grids is used. For the structure, a Lagrangean large-deformation finite element code is employed. The coupled system is solved using a loose coupling algorithm, with position and velocity interpolation and force projection. Several examples, run on parallel machines, demonstrate the range of applicability of the proposed methodology
