IJK Indexing

Formatted (ASCII) External File Option

IJK Indexing,file:filename for Longitudinal Dispersivity,Units(m),file:filename for Transverse Dispersivity,Units(m),

Formatted (ASCII) External File Syntax...

Info

File names must be all lower case and contain text data. Files contain parameter values for every grid-cell ordered according to the indexing scheme (i.e., IJK, JKI, or KIJ). Units shown in the input line will be applied to all parameters in the external file.

Binary External File Syntax...

Info

File names must be all lower case and must contain binary data created with the same FORTRAN compiler used to compile STOMP. Files contain parameter values for every grid-cell ordered according to the indexing scheme (i.e., IJK, JKI, or KIJ). Units shown in the input line will be applied to all parameters in the external file.

Values and files may be used in combination within an input line. For example, when using the IJK Indexing option, the Longitudinal Dispersivity may be specified as a file with varying values, while the Transverse Dispersivity can be specified as a single value for the entire domain.
