class Dumux::AwnSurfacePcMaxFct< ScalarT, ParamsT >

Implementation of an interfacial area surface.

The idea here is to make sure that interfacial area be zero for Sw=1 and pc=pcmax. Because imbibition may have bigger awn than drainage demanding that awn be zero for the whole range of Sw=0 does not fit. However, as we are in primary drainage, demanding that awn=0 for Sw=0 is the same as demanding that awn=0 for pc=pcmax, because Sw=0 cannnot be reached on different ways. We only need to define pcmax ...
