Description

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

Note

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

• 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 \(\mathrm{\overline{S}_w > 1}\)
