Dear Nathan,

I've tried to simulate the welding arc (atmospheric plasma) using FEM
via Ansys. Since, there isn't any element that couples all the
required field (magneto - hydro - thermal), the results were rubish.
Therefore, I went through the Finite Volumes. I've written down my own
code. However, you can use commercials ones, like the traditional
Phoenix or even complete package (I've seen good results from Fluent).

Of course, this is a magnetohydrodynamics formulation (thermal fluid +
Maxwell equations). For Ab initio modelling or Boltzmann lattice
scheme, which in my view is going to be the new trend for
liquid/plasma interactions, you can find them searching physics
journals (for instance, J. Appl. Phys. and J. Phys. D.)
