Can I transfer data through whole computational domain?

Using preCICE

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?

Best regards,
Jun

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.

There are a few pull requests for this on GitHub: Pull requests · precice/openfoam-adapter · GitHub
