smod_equil_RTI – Legolas v. 2.1.1

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.

Note

Default values are given by

k2 = 0
k3 = 1
cte_rho0 = 1 : used in the density profile.
cte_p0 = 1000 : used in the pressure profile, must be large so T0 > 0.
delta = -5 : used in the density profile.
g = 15 : gravitational constant.
alpha = 0 : magnetic shear.
theta = 0.35 $\pi$ : angle used in the velocity profile.
p1 = 0.2 : $v_0$ , used in the velocity profile.
p2 = 0.6 : $v_1$ , used in the velocity profile.
p3 = 0 : $v_2$ , used in the velocity profile.
p4 = -0.35 $\pi$ : $\phi_0$ , used in the magnetic field profile.
tau = 0 : used in the velocity profile.

and can all be changed in the parfile.
