D-R-A-F-T
"front end" computer is being used to create files that will eventually be passed to a
batch-processing computer. On the other hand, files that are referred to as "binary"
or "unformatted" files are specific to the computer on which they were generated.
These files cannot be transferred arbitrarily between computing platforms.
Since SED2D WES requires binary solution files created by GFGEN and RMA2
WES, the user should be aware that same type of computer and compiler should be
used to run each of the models. This will ensure that the binary files are compatible
between runs.
There are numerous files for both input and output.
Input File Description
There are numerous input files required for SED2D. Table 1 shows the required and
optional input data files for SED2D WES. Although this may seem overly complex,
the typical SED2D simulation would require only a small subset of these possiblities.
