The M3D-C1 approach to simulating 3D 2-fluid magnetohydrodynamics in magnetic fusion experiments

Abstract

A new approach for solving the 3D MHD equations in a strongly magnetized toroidal plasma is presented which uses high-order 2D finite elements with C1 continuity. The vector fields use a physics-based decomposition. An efficient implicit time advance separates the velocity and field advance. ITAPS (SCOREC) adaptivity software and TOPS solvers are used. © 2008 IOP Publishing Ltd.
