If the key words 'dp,' 'dual porosity,' or 'fractured' appear in the rock/soil name specified in the Rock/Soil Zonation Card, this indicates a dual porosity medium and the reading of both matrix and fracture properties (e.g., Fracture and Matrix Porosity) is triggered.

File names and format
File names are case sensitive and contain text data and must contain binary data created with the same FORTRAN compiler used to compile STOMP. Files contain one value for each grid cell.
If the key words 'dp,' 'dual porosity,' or 'fractured' appear in the rock/soil name specified in the Rock/Soil Zonation Card, this indicates a dual porosity medium and the reading of both matrix and fracture properties (e.g., Fracture and Matrix Porosity) is triggered.

If the Compressibility Reference Pressure is defaulted (i.e., null entry) then the initial grid-cell pressure will be used as the reference pressure. Reference pressures are recorded in the restart file.

Choose one tortuosity factor model option
...constant,Aqueous Tortuosity Factor,Gas Tortuosity Factor,
...Millington and Quirk,
...Millington-Gas,Gas Tortuosity Factor,
,
Values and files may be used in combination within an input line. For example, when using the IJK Indexing option, the Total porosity may be specified as a file with varying values, while the Particle Grain Density and Specific Storage can be specified as a single value for the entire domain.
