Detailed Description
Problem generator for thermal instability.
PURPOSE: Problem generator for thermal instability. Setup to use the Koyama & Inutsuka cooling function, so must use cgs units for calculations
TI test w/ Isotropic Conduction - hydro The coefficient of conductivity kappa should be defined in cgs unit
TI test w/ Anisotropic Conduction - mhd The coefficient of Spitzer Coulombic conductivity should be given.
Various test cases are possible
- (iprob=1) : TI test w/ isotropic conduction in 1D - sinusoidal fluctuations
- (iprob=2) : TI test w/ isotropic conduction in 2D with sinusoidal fluctuations along the diagonal
- (iprob=3) : TI test w/ conduction in 2D with random pressure purtubation in case of anisotropic conduction : mhd - Diagonal field line
- (iprob=4) : TI test w/ conduction in 2D with random pressure purtubation in case of anisotropic conduction : mhd - Tangled field line
