The goal of the ONELAB interface is to provide a simple communication layer between the solver(s) and Gmsh. You could e.g. take the simple Python solver example, and call your Fortran code from there with a simple system call. Since the Python code will have access to the ONELAB parameters, you could use it to generate the input file for your Fortran solver.
