To verify that MODFLOW is installed, select Model|Program Locations. If it isn't, the edit box where it should be specified will be colored red. If it isn't installed, you can click on the URL above the edit box to open a web browser and navigate to the MODFLOW-2005 page. You can then download and install it. If it is installed but not at the location specified in the dialog box, click the button next to the edit box, navigate to where it is installed and select it.
To run the model, select File|Export|MODFLOW-2005 Input Files . Select the name of the name file to export and the model will be exported. The rest of the files for the model will have the same name as the name file except that the file extension will be changed. By default, the file name will be the same as the ModelMuse file name with the extension changed to ."nam."
ModelMonitor will display the percent discrepancy in the model as the model runs. The model should finish almost immediately. Close ModelMonitor. Then close the listing file and the command line (DOS) window.
