Description

template<class ScalarT>
class Dumux::VanGenuchtenParams< ScalarT >

Specification of the material parameters for the van Genuchten-Mualem constitutive relations.

In this implementation setting either the \(\mathrm{n}\) or \(\mathrm{m}\) shape parameter automatically calculates the other. I.e. they cannot be set independently.

operator==()

template<class ScalarT>

template<class OtherParams>

bool Dumux::VanGenuchtenParams< ScalarT >::operator== ( const OtherParams & otherParams ) const

inline

Equality comparison with another set of params.

setVgAlpha()

template<class ScalarT>

void Dumux::VanGenuchtenParams< ScalarT >::setVgAlpha ( Scalar v )

inline

Set the \(\mathrm{\alpha}\) shape parameter \(\mathrm{[1/Pa]}\) of van Genuchten's curve.

setVgl()

template<class ScalarT>

void Dumux::VanGenuchtenParams< ScalarT >::setVgl ( Scalar l )

inline

Set the pore-connectivity parameter \(\mathrm{l}\) ( \(\mathrm{[-]}\)) of Mualem's relative permeability curve.

Note

In the orignal Mualem (1976) paper the pore-connectivity parameter is called "n". It's referred to as "l" in several later publication of van Genuchten, e.g. van Genuchten (1991), Shaap & van Genuchten (2006).

setVgm()

template<class ScalarT>

void Dumux::VanGenuchtenParams< ScalarT >::setVgm ( Scalar m )

inline

Set the \(\mathrm{m}\) shape parameter \(\mathrm{[-]}\) of van Genuchten's curve.

The \(\mathrm{n}\) shape parameter is set to \(\mathrm{n = \frac{1}{1 - m}}\)

setVgn()

template<class ScalarT>

void Dumux::VanGenuchtenParams< ScalarT >::setVgn ( Scalar n )

inline

Set the \(\mathrm{n}\) shape parameter \(\mathrm{[-]}\) of van Genuchten's curve.

The \(\mathrm{n}\) shape parameter is set to \(\mathrm{m = 1 - \frac{1}{n}}\)

vgAlpha()

template<class ScalarT>

Scalar Dumux::VanGenuchtenParams< ScalarT >::vgAlpha ( ) const

vgm()

template<class ScalarT>

Scalar Dumux::VanGenuchtenParams< ScalarT >::vgm ( ) const

inline
