Is it possible to send data from a Fortran program to Python using MPI?

Question

I am working on a tool to model wave energy converters, where I need to couple two software packages to each other. One program is written in Fortran, the other one in C++.

Answer 1

I would not use MPI for that purpose (unless parallel execution of the code is explicitly required). If your goal is to connect routines written in Fortran, C++ and Python then I suggest writing the (main) connecting part in Python while creating adaptors for your Fortran and C++ routines in order to import them in Python. Then you can manage all function calls in the main Python program and send data around as you wish.
