Also provide a steady-state case?

[BenjaminRodenberg]

An example case is flow-over-heated-plate-steady-state, but we could also prepare a variant of the partitioned heat equation for steady state.

I have a working flow-over heated plate steady-state example now: https://github.com/nemocrys/dolfinx-openfoam/tree/main/steady_state (I still want to improve the FEniCS participant a bit). It uses a slightly different setup than https://precice.org/tutorials-flow-over-heated-plate-steady-state.html, it is all in 2D - similar to the transient case.

How shall we proceed with the OpenFOAM setup? Add it to this repository until there is another solution?

[BenjaminRodenberg]

That's great and it looks like we are almost there. Two main points I see:

• Why is the setup different? We try to use identical setups for all solver combinations to make them easier to compare. If possible, we should try to use the OpenFOAM setup from the tutorials. Is this possible? Then we can (just like for the other cases) store the FEniCS-X solver in this repository as long as the adapter is under development. As soon as we have a stable API we can move everything to the tutorials repository.
• We should make sure that the results for OpenFOAM-OpenFOAM and OpenFOAM-FEniCS-X are identical. From our reference paper we already have some experience with comparing results for the non-steady case. I think we don't have to change a lot here. You can find the script for comparison here.
