smod_equil_isothermal_atmosphere Submodule

This submodule defines an equilibrium in Cartesian geometry with a stratified equilibrium profile, representing a solar magnetic atmosphere. The equilibrium is isothermal with a constant magnetic field. The scale height is given by $$H = \frac{\text{cte_T0}}{g}$$ The geometry is fixed to Cartesian, boundaries can be overridden using the parfile.

This equilibrium is taken from Nye, A., & Thomas, J. (1976). Solar magneto-atmospheric waves. I. An exact solution for a horizontal magnetic field. The Astrophysical Journal, 204. 573-581.
