Functions/Subroutines

impure subroutine, public s_relaxation_solver (q_cons_vf)
 This subroutine should dispatch to the correct relaxation solver based some parameter. It replaces the procedure pointer, which CCE is breaking on.
impure subroutine, public s_initialize_phasechange_module
 The purpose of this subroutine is to initialize the phase change module by setting the parameters needed for phase change and selecting the phase change module that will be used (pT- or pTg-equilibrium).
subroutine, public s_infinite_relaxation_k (q_cons_vf)
 This subroutine is created to activate either the pT- (N fluids) or the pTg-equilibrium (2 fluids for g-equilibrium) model, also considering mass depletion, depending on the incoming state conditions.
subroutine s_infinite_pt_relaxation_k (j, k, l, mfl, ps, p_infpt, q_cons_vf, rhoe, ts)
 This auxiliary subroutine is created to activate the pT-equilibrium for N fluids.
subroutine s_infinite_ptg_relaxation_k (j, k, l, ps, p_infpt, rhoe, q_cons_vf, ts)
 This auxiliary subroutine is created to activate the pTg-equilibrium for N fluids under pT and 2 fluids under pTg-equilibrium. There is a final common p and T during relaxation.
elemental subroutine s_tsat (psat, tsat, tsin)
 This auxiliary subroutine finds the Saturation temperature for a given saturation pressure through a newton solver.
impure subroutine, public s_finalize_relaxation_solver_module
 This subroutine finalizes the phase change module.
