computePressureDifferences()

void RelaxationPFinite::computePressureDifferences	(	Cell *	cell,
		Prim	type = vecPhases )

Compute the pressure differences.

Call for this method computes pressure differences used for relaxation terms.

Parameters

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

relaxation()

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

overridevirtual

Finite Pressure relaxation method.

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

Parameters

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

Reimplemented from Relaxation.

Here is the call graph for this function:

system_relaxation()

void RelaxationPFinite::system_relaxation ( double , double * y, double * ydot, void *  )

static

System of equations to integrate for the LSODA solver.

This method is called by LSODA solver and it computes the time derivatives of the system in function of the primitive variables.

Parameters

t	time
y	primitive variables
ydot	time derivatives
data	pointer to data not contained in t and y
