Mesh Generation and Control for Moving Boundary Problems

In this proposal, a team comprising of HyPerComp Inc. and NASA-JPL aims to develop modular parallel adaptive meshing capability for problems involving implicitly captured interfaces such as free surface capture using the level set method. In specific, these models will be demonstrated along with the appropriate software interfaces for the US Army PROTEUS toolkit. The foundation for this development will be an existing full-featured mesh generation program which has capabilities to handle geometries defined by CAD models as well as pointwise/mesh based data. This code will be interfaced with the open source software PYRAMID (developed and supported at JPL) and an API-based communication between PROTEUS (and other internally developed solvers) and the mesh modules will be developed. The effects of curved geometry (which can be important in high order modeling), scalability and efficiency of the parallel adaptive algorithm, smoothness of the mesh, preserving high order accuracy and stability in the simulation process shall be the highlights of the proposed project. HyPerComp has a long record of accomplishments in mesh generation for large scale fluid mechanics and electromagnetics problems, as well as modern high performance computing techniques in these areas. The parallel adaptive mesh software at JPL is one among a select group of computer programs with well demonstrated capabilities.
