Functions/Subroutines
subroutine, public	s_pressure_relaxation_procedure (q_cons_vf)
	The main pressure relaxation procedure.
impure subroutine, public	s_report_pressure_relaxation
	One line at the end of a run if the equilibration ever stopped on its iteration cap. Silence means every cell reached the tolerance.
logical function	s_needs_pressure_relaxation (q_cons_vf, j, k, l)
	Check if pressure relaxation is needed for this cell.
subroutine	s_correct_volume_fractions (q_cons_vf, j, k, l)
	Correct volume fractions to physical bounds.
subroutine	s_equilibrate_pressure (q_cons_vf, j, k, l, hit_cap, resid, unusable)
	Main pressure equilibration using Newton-Raphson.
subroutine	s_correct_internal_energies (q_cons_vf, j, k, l, rho, gamma, pi_inf, qv_mix)
	Correct internal energies using equilibrated pressure.

Variables
integer	n_hit_cap = 0
	Cell updates in which the Newton below stopped on its iteration cap rather than on the tolerance. Counted because the answer then depends on that cap, and nothing else in the code says so.
real(wp)	worst_residual = 0._wp
	Largest |f| left behind when the cap was reached.

Variable Documentation

n_hit_cap

integer m_pressure_relaxation::n_hit_cap = 0

Cell updates in which the Newton below stopped on its iteration cap rather than on the tolerance. Counted because the answer then depends on that cap, and nothing else in the code says so.

Definition at line 361 of file m_pressure_relaxation.fpp.f90.

worst_residual

real(wp) m_pressure_relaxation::worst_residual = 0._wp

Largest |f| left behind when the cap was reached.
