Select Single-Phase Flow GeoApps  to access pre-defined macros included in GeoDict:

They can be edited with a standard text editor. To open the corresponding *.py file for a predefined macro, click the Open Macro / Script File button. After making changes to the script, you can either store the modified macro locally and run it from the main menu Macro → Execute Macro Script or as an administrator you may store it in its original place and make the modified version available to all users. Refer to the GeoApp User Guide.

To use a predefined macro, select it from the pull-down menu, click the Edit… button to set the parameters, and then the Run button to run the simulation.
