A constrained transport divergence-free finite element method for Incompressible MHD equations
Lingxiao Li, Donghang Zhang, Weiying Zheng
In this paper we study finite element method for three-dimensional incompressible resistive magnetohydrodynamic equations, in which the velocity, the current density, and the magne…
