Structure preserving transport stabilized compatible finite element methods for magnetohydrodynamics
Golo A. Wimmer, Xianzhu Tang
We present compatible finite element space discretizations for the ideal compressible magnetohydrodynamic equations. The magnetic field is considered both in div- and curl-conformi…
