OpenFOAM MPI coupling

I am not a current user of OpenFOAM but I might be soon ;)

I have an external software that I wish to call at certain times for some of the computational cells. I wish to distribute the calls to this external software evenly in an array using MPI. I wonder if it is possible to invoke MPI commands in user defined functions (or whatever it is called in OF)?

Best Regards

With OpenFoam you get access to the source code, so you can do anything you want. You probably don't even have to dig that deep to add the calls.

Ok, thank you.

Any useful information on where to begin digging?
