I found that in the official PreCICE case, compressible solvers were rarely used. If I want to use the compressibleInterDyMFoam solver, how should I modify the fvSchemes and fvSolution files? I tried to modify the fvSchemes and fvSolution files in interFoam in the breaking-dam-2d example, but I kept reporting errors.

Some examples that might help:

- buoyantPimpleFoam: [Flow over heated plate | preCICE - The Coupling Library](https://precice.org/tutorials-flow-over-heated-plate.html)
- sonicLiquidFoam: [Partitioned pipe flow | preCICE - The Coupling Library](https://precice.org/tutorials-partitioned-pipe.html)
- interFoam: [Partitioned pipe two phase | preCICE - The Coupling Library](https://precice.org/tutorials-partitioned-pipe-two-phase.html)

They can definitely be improved and your solver is different (and probably old, given the `DyM` in the name), but might lead somewhere.

Does the uncoupled fluid case work?
