A spectral/hp element MHD solver

Computational Physics 2019-01-23 v4

Abstract

A new MHD solver, based on the Nektar++ spectral/hp element framework, is presented in this paper. The velocity and electric potential quasi-static MHD model is used. The Hartmann flow in plane channel and its stability, the Hartmann flow in rectangular duct, and the stability of Hunt's flow are explored as examples. Exponential convergence is achieved and the resulting numerical values were found to have an accuracy up to 101210^{-12} for the state flows compared to an exact solution, and 10510^{-5} for the stability eigenvalues compared to independent numerical results.
