TITLE: Tools and Techniques for Mesh Repair in Rocket Simulation

ABSTRACT

The Center for Simulation of Advanced Rockets (CSAR) conducts research on the whole-system simulation of solid propellant rockets. Important subsystems include solid mechanics of the propellant and fluid dynamics of the interior flow and exhaust plume. The evolving geometry of solid propellant and interior flow requires adaptive meshing. The adaptive meshing techniques we use include mesh smoothing, local mesh repair, and global remeshing. This talk will focus on local mesh repair and global remeshing. Recently CSAR has acquired a software suite MeshSim from Simmetrix Inc. that includes both serial and parallel mesh adaptation tools. We will present the capabilities of MeshSim and our plans for deploying MeshSim in the integrated Rocstar rocket simulation code suite.
