Description

template<class Scalar>
class Dumux::FluidMatrix::VanGenuchtenRegularization< Scalar >

A regularization for the VanGenuchten material law.

Note

Regularization can be turned of by setting the threshold parameters out of range (runtime) or by replacing this class by NoRegularization (compile time).

operator==()

template<class Scalar>

bool Dumux::FluidMatrix::VanGenuchtenRegularization< Scalar >::operator== ( const VanGenuchtenRegularization< Scalar > & o ) const

pc()

template<class Scalar>

OptionalScalar< Scalar > Dumux::FluidMatrix::VanGenuchtenRegularization< Scalar >::pc ( const Scalar swe ) const

inline

The regularized capillary pressure-saturation curve regularized part:

• low saturation: extend the \(\mathrm{p_c(S_w)}\) curve with the slope at the regularization point (i.e. no kink).
• high saturation: connect the high regularization point with \(\mathrm{\overline{S}_w =1}\) with a spline and continue linearly for \(\mathrm{\overline{S}_w > 1}\)

swe()

template<class Scalar>

OptionalScalar< Scalar > Dumux::FluidMatrix::VanGenuchtenRegularization< Scalar >::swe ( const Scalar pc ) const

inline

The regularized saturation-capillary pressure curve.
