| 16 | #include <dumux/porousmediumflow/fvspatialparamsmp.hh> | ||

| 22 | // In the TwoPTestSpatialParams class we define all functions needed to describe the porous matrix, e.g. porosity and permeability. We inherit from the `FVPorousMediumFlowSpatialParamsMP` class, which is the base class for multiphase porous medium flow applications. | ||
