◆ capillaryPressure()

template<class Traits >

Scalar Dumux::ExtendedRichardsVolumeVariables< Traits >::capillaryPressure ( ) const

inline

The capillary pressure is defined as the difference in pressures of the nonwetting and the wetting phase, i.e.

\[ p_c = p_n - p_w \]

Note: Capillary pressures are always larger than the entry pressure This regularization doesn't affect the residual in which pc is not needed.

◆ density()

template<class Traits >

Scalar Dumux::ExtendedRichardsVolumeVariables< Traits >::density ( const int phaseIdx = liquidPhaseIdx ) const

inline

Parameters

phaseIdx The index of the fluid phase

◆ extrusionFactor()

template<class Traits >

Scalar Dumux::PorousMediumFlowVolumeVariables< Traits >::extrusionFactor ( ) const

inlineinherited

This means the factor by which a lower-dimensional (1D or 2D) entity needs to be expanded to get a full dimensional cell. The default is 1.0 which means that 1D problems are actually thought as pipes with a cross section of 1 m^2 and 2D problems are assumed to extend 1 m to the back.

const FluidState & Dumux::ExtendedRichardsVolumeVariables< Traits >::fluidState ( ) const

inline

Parameters

phaseIdx	The phase index
compIdx	The component index

◆ mobility()

template<class Traits >

Scalar Dumux::ExtendedRichardsVolumeVariables< Traits >::mobility ( const int phaseIdx = liquidPhaseIdx ) const

inline

The mobility of a fluid phase is defined as the relative permeability of the phase (given by the chosen material law) divided by the dynamic viscosity of the fluid, i.e.

\[ \lambda_\alpha := \frac{k_{r\alpha}}{\mu_\alpha} \]

Parameters

phaseIdx The index of the fluid phase

The porosity is defined as the ratio of the pore space to the total volume, i.e.

\[ \Phi := \frac{V_{pore}}{V_{pore} + V_{rock}} \]

◆ pressure()

template<class Traits >

Scalar Dumux::ExtendedRichardsVolumeVariables< Traits >::pressure ( const int phaseIdx = liquidPhaseIdx ) const

inline

For the nonwetting phase (i.e. the gas phase), we assume infinite mobility, which implies that the nonwetting phase pressure is equal to the finite volume's reference pressure defined by the problem.

phaseIdx The index of the fluid phase

◆ pressureHead()

template<class Traits >

For the nonwetting phase (i.e. the gas phase), we assume infinite mobility, which implies that the nonwetting phase pressure is equal to the finite volume's reference pressure defined by the problem.

Parameters

phaseIdx The index of the fluid phase

Note: this function is here as a convenience to the user to not have to manually do a conversion. It is not correct if the density is not constant or the gravity different
