Detailed Description

template<class TraitsT, class ParamsT = BrooksCoreyParams<TraitsT>>
class Opm::BrooksCorey< TraitsT, ParamsT >

Implementation of the Brooks-Corey capillary pressure <-> saturation relation.

This class provides the "raw" curves as static members and doesn't concern itself converting absolute to effective saturations and vice versa.

The relative permeability-saturation curves.

Parameters
valuesA random access container which stores the relative permeability of each fluid phase.
paramsThe parameter object expressing the coefficients required by the material law.
fsThe fluid state for which the relative permeabilities ought to be calculated
