An In-House Overset Supersonic Solver With Grid Refinement Capability on Parallel Environment

A three-dimensional finite volume method solver that runs on an adaptive overset mesh is developed for supersonic flows. The solver utilizes the open source libraries of p4est and OpenFOAM utilities to generate, maintain, and readapt the computational grids in a distributed memory architecture during parallel runs supported by MPI. We achieve to assemble the overset grid using our newly developed in-house strategy and code. We validated the solver by considering experimental data available in the literature for a supersonic flow over a cylinder with a hemisphere tip.
