Mesh Generation and Control for Moving Boundary Problems

In this STTR project we aim to build software interfaces and enhancements to existing parallel mesh adaptation libraries for applications in high performance flow modeling. In Phase-I we demonstrated a preliminary implementation of such a system and identified technology needs. Phase-II development will include both open source, as well as commercially supported mesh adaptation software and interfaces. Tools will be provided for generating an initial mesh defined by CAD models as well as discretely specified pointwise/surface mesh based data. Highlights of this software will include mesh movement, handling curved geometry, very large scale parallelization, and appropriate mathematical machinery for high order data interpolation, mass and momentum conservation and error estimation in the adapted mesh. We will focus on the mesh generation and adaptation needs of the US Army PROTEUS simulation system in implicit free surface capture (using the level set method). The tools developed, however, will be more generally applicable. The team includes HyPerComp Inc., the Scientific Computation Research Center (SCOREC) at RPI and Simmetrix Inc., comprising of researchers with a long record of contributions in scientific computing and mesh generation.
