MT3DMS Data Requirements
Date requirements for visualizing MT3DMS results are as follows:
- The input parameter
CINACT
must be assigned a value that is different
from simulated concentration at active cells. (See note 1 below.)
- The input parameter
SAVUCN
must be set to T in order to save concentrations.
- Concentrations must be save at one or more transport
time steps.
Note:
- If the simulated concentration at a cell is equal to
CINACT, Model Viewer assumes that the cell is inactive and will not display
it. Therefore, the common practice of setting CINACT to zero should be avoided
if concentrations at active cells might also be zero. Another consideration is
to avoid truncation error. For example, setting CINACT to 99.999 should be
avoided because the output might not be written with adequate precision.
Instead, it is recommended that CINACT be set to a large negative integer such
as -1.0E10.
