◆ CompEquil()

double CompEquil ( double  N,
double  T,
double *  v 
)
Parameters
[in]nthe particle number density (not needed, but kept for compatibility)
[in]Tthe temperature (in K) for which equilibrium must be found.
[in,out]van array of primitive variables. On input, only density needs to be defined. On output, fractions will be updated to the equilibrium values.

Compute the equilibrium ionization balance for (rho,T)

◆ Radiat()

void Radiat ( double *  v,
double *  rhs 
)
