# smod_equil_RTI Submodule

This submodule defines Rayleigh-Taylor instabilities in Cartesian geometry. This equilibrium is a specific case of the flow driven instabilities.

This equilibrium is taken from section 13.2, p. 487 (case a) in Goedbloed, H., Keppens, R., & Poedts, S. (2019). Magnetohydrodynamics of Laboratory and Astrophysical Plasmas. Cambridge University Press. DOI.
