7.2. Porosity
Here, porosity values are assigned within geounits (specified in §6.1.4 Geometries above) using one of the methods described below.
The format for this section of input is:
list Geom.Porosity.GeomNames [no default]
This key specifies all of the geometries on which a porosity will be assigned. These geometries must cover the entire computational domain.
pfset Geom.Porosity.GeomNames "background"
