I’m currently investigating the best way to couple two CFD flow codes. The requirement is that one code solves outer domain of the simulation, and the other code the inner domain with a different kind of solver. Each solver has their own process(es) and grid, and the coupling is intended to be realized with overset grid approach, with minimally invasive code changes.
Today I came across the preCICE framework and it looks very promising, except that - as far as I can see - the coupling is only surface/interface based? Is the overset coupling also possible, or would it be possible to realise this with some changes to the framework, or in the adapter code?
thanks for your insight
