Completely parallel compressible flow simulations using adaptive unstructured meshes

Abstract

New and efficient completely parallel strategies for unstructured mesh solvers with dynamically adaptative meshes are developed. From highly complex academic research problems of unsteady compressible flow simulation to full scale aircraft problems, all are simulated with high performance results. Dynamic load balancing is obtained for simple but robust domain partitioners, who work directly on the network of processors. The code is hybrid as it allows elements of different types to co-exist in the same mesh.
