MF 6 MDT Package
Changes to options and grid data
OPTIONS
- SAVE FLOWS – Save flows to budget file.
- PRINT FLOWS – Print flows to listing file.
- SORPTION – Sorption will be activated. Requires that BULK DENSITY and DISTCOEF.
- FIRST ORDER DECAY – First-order decay will occur.
- TSHIFTMD – Time elapsed since matrix diffusion began. Indicates that the MODFLOW start time (t = 0) is not the starting time of matrix diffusion, and the subsequent real variable.
- MD FILEOUT – Write AIOLD1MD and AIOLD2MD coefficients to a binary file.
GRIDDATA
- Griddata – List of available properties.
- MD_TYPE_FLAG — The matrix diffusion type flag at any location.
- MD_FRACTION – The immobile fraction at any location, i.e., the fraction of the total space that is occupied by the fracture/high permeability domain.
- MD_POROSITY – The effective transport porosity at any location.
- BULK_DENSITY – The dry bulk density of the porous matrix of the matrix domain at any location
- MD_DIFF_LENGTH – The diffusion length for diffusive transport within the matrix domain at any location (only used for embedded heterogeneity).
- MD_TORTUOSITY – The tortuosity of the matrix domain at any location.
- MD_DIST_COEFF – The adsorption coefficient (Kd) of a contaminant species in the immobile domain at any location.
- MD_DECAY – The first-order decay coefficient in water and on soil (1/time) in the matrix domain at any location.
- MD_DIFF_COEFF – The diffusion coefficient of each species component within the matrix domain at any location.
- AIOLD1MD – The concentration integral (equation 8) of each species in an element associated with matrix diffusion into an infinite acting adjacent aquitard (MDFLAG = 1, 3, 4, 5, 6, or 7). This value is used to restart a simulation with prior matrix diffusion.
- AIOLD2MD – The concentration integral (equation 8) of each species in an element associated with matrix diffusion in low permeability zones that are embedded in the volume element (MDFLAG = 2, 5, 6, or 7). This value is used to restart a simulation with prior matrix diffusion.
- Use Constant – Turn on to enter a constant value.
- Constant Value – Enter a constant value for the property.
- Dataset to Array – Clicking the Dataset to Array will open an array editor dialog for the specific property.
