A Discontinuous Galerkin Method for Ideal Magnetohydrodynamics in NRLs JENRE (registered trademark) Code

Abstract

We outline progress made towards the development of a computational model coupling electromagnetic effects with fluid dynamics for use in the study of ionized flows around hypersonic vehicles. The initial progress takes the form of the complete implementation of an ideal magnetohydrodynamics (MHD) solver in NRLs JENRE (registered trademark) multiphysics code. This lays the important groundwork for the implementation of more detailed and realistic modeling capabilities. We outline the numerical methods, implementation, and successful validation of the ideal MHD model in the unstructured computational mesh framework of JENRE (registered trademark), which is novel in the field of MHD and will play a critical role in modeling realistic hypersonic vehicle geometries in the future.
