Hi there,

I have written my numerical solution (for fluid dynamics) in Fortran. I have used Qt to make an application to serve as a GUI for my code.

So far, Qt application takes input from the user and save them in a text file. Then, the text file will serve as input for the Fortran code which solves the problem.
Solving the problem, Fortran saves results back into some other text files which can be loaded into Qt application for further analysis.

I am not expert in application development. My question is that, is this the simple and good way to do GUI and Program-Solver interaction, or should I try other ways?

Thanks for hints.
