mod_thermal_conduction::tc_fluid Type Reference

Public Attributes
double precision	tc_k_para
	Coefficient of thermal conductivity (parallel to magnetic field)
double precision	tc_k_perp
	Coefficient of thermal conductivity perpendicular to magnetic field.
integer	e_ =-1
	Indices of the variables.
integer	tcoff_
	Index of cut off temperature for TRAC.
integer	tc_slope_limiter
	Name of slope limiter for transverse component of thermal flux.
logical	subtract_equi =.false.
logical	tc_constant =.false.
	Logical switch for test constant conductivity.
logical	tc_perpendicular =.false.
	Calculate thermal conduction perpendicular to magnetic field (.true.) or not (.false.)
logical	tc_saturate =.false.
	Consider thermal conduction saturation effect (.true.) or not (.false.)
logical	tc_patch_eint =.false.
	Patch cells where e_int < 0 during STS Chebyshev substeps by neighbor-averaging the temperature. Prevents NaN from sqrt(T<0) in the Spitzer conductivity when the RKL2 polynomial overshoots.
double precision	trac_t_floor =0.d0
	Minimum temperature (code units) below which TRAC does not modify conductivity. Below this T, the energy balance is dominated by optically thick radiation and recombination, not optically thin cooling + Spitzer conduction, so TRAC's broadening assumption does not apply. Read in Kelvin via tc_list (trac_T_floor), converted to code units during init. Default 1e4 K.
double precision	inv_gamma_minus_1
	EoS snapshots + inverse accessor (set in bind_eos_to_source); let TC reach thermodynamics only through this object, never mod_eos directly.
double precision	nh2rhofactor
double precision	log_t_floor
