Description

Originally posted by @BenjaminRodenberg in https://github.com/precice/tutorials/pull/406#pullrequestreview-1809133053

I guess there was already an error/inaccuracy (compared to the FEniCS case) in how you are treating the boundary conditions before. I would suggest to open an issue and try to fix this to reach the same accuracy as for the FEniCS case without subcycling in a separate PR. Not sure whether this is actually possible with OpenFOAM: In FEniCS, I needed 2nd order FEM to do the trick with the flux. I have no idea about the capabilities of OpenFOAM and FV here.
