Microstructure Properties#
Microstructure property models address material parameters and constitutive equations required for multiphase continuum approaches to flow in porous media, viz. fluid flow in partially or fully saturated porous media. Actually, only a few of these model/property cards pertain directly to media structure or microstructure, but all are affected by intrinsic material properties of all involved phases. Cards or records typically appearing in this section fall into one of three categories: microstructural or flow-property specification, numerical treatment specification, and species transport property specifications. These “sections” appear in this order in most of the sample input files.
