[case] SaturationExponential

A simplistic soil characteristics function.

This property must be a medium property. It computes the saturation of the wetting phase as function of capillary pressure.

The capillary pressure-saturation relationship given by \(S_{eff}=1-\left(\frac{p_{c}}{p_{c}^{max}}\right)^{\lambda}\), where \(\lambda\) is an exponent, \(p_{c}\) is capillary pressure, \(p_{c}^{max}\) is the maximum capillary pressure at which \(S_{eff}=0\).

This property can mainly be used for testing. If the exponent is set to 1, the characteristic curve shows a linear dependence.

Reference capillary pressure at which \(S_{eff}=0\).
