void TpfaCompressibleAssembler::assemble	(	const double *	sources,
		const FlowBCTypes *	bctypes,
		const double *	bcvalues,
		const double	dt,
		const double *	totcompr,
		const double *	voldiscr,
		const double *	cellA,
		const double *	faceA,
		const double *	wellperfA,
		const double *	phasemobf,
		const double *	phasemobwellperf,
		const double *	cell_pressure,
		const double *	gravcapf,
		const double *	wellperf_gpot,
		const double *	surf_dens
	)

inline

Assemble the sparse system. You must call init() prior to calling assemble().

Parameters

sources	Source terms, one per cell. Positive numbers are sources, negative are sinks.
total_mobilities	Scalar total mobilities, one per cell.
omegas	Gravity term, one per cell. In a multi-phase flow setting this is equal to $\omega = \sum_{p} \frac{\lambda_p}{\lambda_t} \rho_p$ where $\lambda_p$ is a phase mobility, $\rho_p$ is a phase density and $\lambda_t$ is the total mobility.

void TpfaCompressibleAssembler::computePressuresAndFluxes	(	std::vector< double > &	cell_pressures,
		std::vector< double > &	face_pressures,
		std::vector< double > &	face_fluxes,
		std::vector< double > &	well_pressures,
		std::vector< double > &	well_fluxes
	)

inline

Compute cell pressures and face fluxes. You must call assemble() (and solve the linear system accessed by calling linearSystem()) prior to calling computePressuresAndFluxes().

Parameters

[out]	cell_pressures	Cell pressure values.
[out]	face_areas	Face flux values.

double TpfaCompressibleAssembler::explicitTimestepLimit	(	const double *	faceA,
		const double *	phasemobf,
		const double *	phasemobf_deriv,
		const double *	surf_dens
	)

inline

Explicit IMPES time step limit.

void TpfaCompressibleAssembler::explicitTransport	(	const double	dt,
		double *	cell_surfvols
	)

inline

Explicit IMPES transport.

void TpfaCompressibleAssembler::faceFluxToCellFlux	(	const std::vector< double > &	face_fluxes,
		std::vector< double > &	cell_fluxes
	)

inline

Compute cell fluxes from face fluxes. You must call assemble() (and solve the linear system accessed by calling linearSystem()) prior to calling faceFluxToCellFlux().

Parameters

	face_fluxes
	face_areas	Face flux values (usually output from computePressuresAndFluxes()).
[out]	cell_fluxes	Cell-wise flux values. They are given in cell order, and for each cell there is one value for each adjacent face (in the same order as the cell-face topology of the grid). Positive values represent fluxes out of the cell.

		const double *	perm,
		const double *	porosity,
		const typename Grid::Vector &	gravity
	)

inline

Initialize the solver's structures for a given grid, for well setup also call initWells().

Template Parameters

Grid	This must conform to the SimpleGrid concept.
Wells	This must conform to the SimpleWells concept.

Parameters

grid	The grid object.
wells	Well specifications.
perm	Permeability. It should contain dim*dim entries (a full tensor) for each cell.
perm	Porosity by cell.
gravity	Array containing gravity acceleration vector. It should contain dim entries.
