The MT3DMS Basic Transport Package dialog can be used to edit a series of input arrays including ICBUND, starting concentrations, and porosity. The longitudinal dispersivity array is defined in the Dispersion Package dialog. Furthermore, if the Cell by cell input option is selected in the Chemical Reactions Package dialog, arrays must be defined for bulk density, sorption constants, and rate constants. All three dialogs contain buttons that bring up a spreadsheet dialog for editing the array or copying interpolated data sets into the array.
Another method for editing these arrays is the Cell Properties command in the MT3D menu. Before selecting the Cell Properties command, a set of cells should be selected using the cell selection tools. Once the command is selected, the MT3DMS Cell Properties dialog appears.
The parameters for the selected cells are changed by typing in new values in the edit fields and selecting the OK button. For some of the parameters, a value must be entered for each species.
If more than one cell is selected when the Cell Properties command is selected, the edit fields will appear blank. To edit one of the parameters, enter a value in the field. When the OK button is selected, only the parameters whose fields do not appear blank are changed. This makes it possible to change one of the parameters (e.g., porosity) for all of the selected cells while leaving the other parameters unchanged.
