Is there a graphics user interface (GUI) for GprMax?

I have not developed a GUI for GprMax as it was developed to work on UNIX mainframes and not run interactively. However, GprMax can run interactively if you wish and is very simple to use in either MSWindows, Linux or Macs.  The input to GprMax is a simple text (ASCII) file that can be created in any text editor. This input file contains the commands that build the geometry and other information that is required to run a model.

In the future a GUI frontend might be developed for GprMax althought this is not a priority!
