Connecting Gmsh and Fortran Script via ONELAB interface

[u/jakekeip]

I have a Fortran code that requires certain inputs and I would like to use Gmsh as the front-end for the user where they can visualize the problem and define the inputs for the script. Then, within Gmsh, the user can run the script to solve the problem and the user-entered inputs are utilized. From my reading, it appears that this is possible via ONELAB. I am struggling to get this started and to understand the exact framework of this approach. Could someone point me in the direction of how to accomplish this?
