Description
This command selects as a parameter the aperture of a parallel plate fracture
model. The single fracture must be modeled as a 1D or 2D model of thickness
1 meter, i.e., aperture must be identical to porosity.
Furthermore, the capillary pressure model must contain a parameter CP(2,NMAT)
which represents the gas entry pressure (e.g., BrooksCorey (ICP=10),
van Genuchten (ICP=11)). The parallel plate model relates porosity phi,
permeability k [m^{2}], and gas entry pressure p_{e} [Pa] to aperture a [m]
as follows:
k = a^{3}/12
p_{e} = 0.14366/a
