smod_equil_gravito_mhd Submodule

This submodule defines an equilibrium in Cartesian geometry with a stratified equilibrium profile, giving rise to gravito-MHD waves. The geometry can be overridden using the parfile.

This equilibrium is taken from section 7.3.3, p. 258 in Goedbloed, H., Keppens, R., & Poedts, S. (2019). Magnetohydrodynamics of Laboratory and Astrophysical Plasmas. Cambridge University Press. DOI.
