Detailed Description

template<class TypeTag>
class Opm::DarcyExtensiveQuantities< TypeTag >

Provides the Darcy flux module.

The commonly used Darcy relation looses its validity for Reynolds numbers $ Re <
1$ . If one encounters flow velocities in porous media above this threshold, the Forchheimer approach can be used.

The Darcy equation is given by the following relation:

$\‍[ \vec{v}_\alpha = \left( \nabla p_\alpha - \rho_\alpha \vec{g}\right) \frac{\mu_\alpha}{k_{r,\alpha} K} \‍]$

◆ calculateBoundaryFluxes_()

template<class TypeTag>

void Opm::DarcyExtensiveQuantities< TypeTag >::calculateBoundaryFluxes_	(	const ElementContext &	elemCtx,
		unsigned	boundaryFaceIdx,
		unsigned	timeIdx )

inlineprotected

Calculate the volumetric fluxes at a boundary face of all fluid phases.

The pressure potentials and upwind directions must already be determined before calling this method!

◆ calculateBoundaryGradients_()

template<class TypeTag>

template<class FluidState>

void Opm::DarcyExtensiveQuantities< TypeTag >::calculateBoundaryGradients_	(	const ElementContext &	elemCtx,
		unsigned	boundaryFaceIdx,
		unsigned	timeIdx,
		const FluidState &	fluidState )

inlineprotected

Calculate the gradients at the grid boundary which are required to determine the volumetric fluxes.

The the upwind directions is also determined by method.
