analyticalPressure()

double RelaxationPT::analyticalPressure	(	Cell *	cell,
		Prim	type = vecPhases ) const

Pressure determination with analytical formulae for 2 phases governed by SG or IG EOS.

call for this method determines the pressure using the analytical formulae only valid in the specific case of 2 phases governed by SG or IG EOS

Parameters

cell	cell to relax
type	enumeration allowing to relax either state in the cell or second order half time step state

Returns

pressure

analyticalTemperature()

double RelaxationPT::analyticalTemperature	(	double	pressure,
		Cell *	cell,
		Prim	type = vecPhases ) const

Temperature calculus with analytical formulae for N phases governed by SG or IG EOS.

call for this method computes the temprerature for N phases governed by SG or IG EOS using the known relaxed pressure

Parameters

pressure	the value of relaxed pressure
cell	cell to relax
type	enumeration allowing to relax either state in the cell or second order half time step state

Returns

temperature

Return the pressure- and temperature-relaxation type.

Reimplemented from Relaxation.

relaxation()

void RelaxationPT::relaxation ( Cell * cell, const double & , Prim type = vecPhases )

overridevirtual

Stiff Pressure-Temperature relaxation method.

call for this method computes the mechanical and thermal relaxed state in a given cell. Relaxed state is stored depending on the type enum

Parameters

cell	cell to relax
dt	time step (not used here)
type	enumeration allowing to relax either state in the cell or second order half time step state

Reimplemented from Relaxation.
