Hello,
I want to transfer volume fraction from OpenFOAM multiphase solver (interFoam) to other solver. I saw many examples transfer the data through interface, which is a patch in 0/ file. But I want to transfer the alpha (volume fraction) through the whole computational domain. I don’t find any instructions to do this? is this feasible in preCICE? Someone have suggestions on this?
You essentially want to do volume coupling. There are a few prototypes for this out there and we are now working on adding full support for volume coupling in the OpenFOAM adapter.
