◆ capillaryPressure()

template<class Traits >

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

inline

Returns the effective capillary pressure \(\mathrm{[Pa]}\) within the control volume.

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.

		FluidState &	fluidState,
		SolidState &	solidState
	)

inline

Fills the fluid state according to the primary variables.

Taking the information from the primary variables, the fluid state is filled with every information that is necessary to evaluate the model's local residual.

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.
