Running external application in solver

dariodario32 · July 9, 2017, 14:47

Hi all,
I'm trying to write a new solver for FSI applications.
I was able to use the OF libraries to map the pressure and shear stress on the structural solver. I would like to know if it is possible to write a new solver in OF that can call the structural solver (in a way that everything is automatic), avoiding the interaction of the user through the command line.

Thanks

You could use a system call to execute your other application from your OF solver. I'm not sure whether this will "freeze" your OF solver until the structural solver returns, but I suppose that it will.

Disadvantage: portability.
Advantage: if the user can execute it, your OF solver can also execute it very easily

Alternatively, you can link your OF solver to your structural solver by importing the appropriate headers of the structural code in your OF solver and then you can call the main function of your structural solver to get it rolling.

Advantage: portability.
Disadvantage: more work, and requires access to the source of the structural solver
