WMS:MODRAT Run Simulation

Once the data for MODRAT input have been defined, the MODRAT model may be launched directly from WMS.

The Run MODRAT dialog provides two options for running a MODRAT model:

1. Create a new MODRAT input file from the data in WMS and run it. To do this, make sure the "Save file before run" checkbox is checked, then click the Input File button, browse to the folder where you want to save the MODRAT input and output files and enter a new filename for the MODRAT input file. Note that the option to specify the prefix for output files from MODRAT is active with this option. This provides a reminder of the name specified in the Job Control dialog, and allows you to change the name if desired. WMS will save a *.lac file (standard MODRAT input), and *.dat for rainfall input, and reservoir or input hydrograph files if necessary.
2. Run MODRAT with an existing input file. To do this, make sure the Save file before run is unchecked, then click the Input File button and choose the file you wish to input to MODRAT. Click OK in the Run MODRAT dialog to launch the model run. WMS will not save any files to disk - it will just launch the model. The MODRAT model will run and write the standard output files.

Once an input file has been specified and you select OK, MODRAT will be executed. A separate window will appear and information about the MODRAT simulation will be reported. If MODRAT is not executed successfully when issuing this command, be sure that the path to the MODRAT.EXE file is correct. If MODRAT does not run to a successful completion you can view the ASCII output file using the View File command in the File menu.
