摘要：
A new MHD solver based on the Nektar++ spectral/hp element framework is presented in the paper. A velocity and electric potential quasi-static MHD model is used. The Hartmann flow in a plane duct and its stability, the Hartmann flow in a rectangular duct, and the stability of Hunt's flow are studied as examples. Exponential convergence is achieved and resulting numerical values have been found to have an accuracy up to 10(-12) for state flows compared to an exact solution, and to 10(-5) for stability eigenvalues compared to independent numerical results.
