MODFLOW Packages and Programs Dialog Box

The MODFLOW Packages and Programs dialog box is used to specify non-spatial input required by the various MODFLOW packages, MODPATH, ZONEBUDGET, and MT3DMS. To display the MODFLOW Packages and Programs dialog box, select Model|MODFLOW Packages and Programs... The "Parameters" used by the various packages, the choice of solver used to solve the equations in MODFLOW, and the convergence criterion in the Lake package are among the items specified in the MODFLOW Packages and Programs dialog box.

The left side of the MODFLOW Packages and Programs dialog box has a tree control that shows the MODFLOW packages supported by ModelMuse. Next to the name of each package is either a radio button or a checkbox. A package will be included in the MODFLOW model if its checkbox or radio button is checked. The data for each package will be shown in the pane on the right side of the MODFLOW Packages and Programs dialog box when its name is selected.

In many cases, the full name of a package will be too long to be fully displayed in the tree control. However, when a mouse is held over the portion of the name that is visible, the full name will be displayed in a small popup window. In addition, the width of the tree control can be changed by clicking on the area just to the right of the tree control and dragging it so that the width of the tree becomes larger or by resizing the entire dialog box.

For most packages, MODFLOW will accept comments at the beginning of the input file and will then print them in the output file. Even for those package that do not have this capability, such as the Lake package, ModelMuse provides a space to write such comments. Such comments can be useful for documenting why particular values in the input were selected.

The Gage package is not activated in the MODFLOW Packages and Programs dialog box. Instead, if any gages are defined in the SFR or LAK packages, the Gage package will be activated.
