Non-dimensionalizing the Ideal MHD System

It depends on what kind of physics you're interested in, but typically for MHD I tend to normalize the magnetic field energy to match the fluid energy: \begin{gather} e_0 = m_0 n_0 V_0^2\\ P_0 = e_0\\ ...

How to impose boundary conditions when solving a nonlinear dynamical system given by the FEM solver

The general approach in a Newton method is to solve for increments $\delta u$. Then, if your current solution already has the right values at the boundary, $\delta u$ needs to have zero boundary ...
