Another situation where this bug is visible: `SolverOne.py`: ``` import precice solverInterface = precice.Interface("SolverOne", "precice-config.xml", 0,1) #solverInterface.initialize() # waiting for SolverTwo's solverInterface.initialize() # ERROR: The provided mesh "MeshOne" is empty....

Shifting it to `3.x.x`, because it is not critical in my opinion. Feel free to shift it back to `3.0.0`, if you are willing to work on it.

It's to some degree an open question where we want to go from here: I added adaptive time stepping and use time interpolation in this PR. This is similar to...

I did a quick round of checks for the newly added `requirements.txt` and modified `./run.sh` script and everything works. Thanks for adding @NiklasVin !

I did a final round of testing and will merge this PR now.

The assertion is obviously wrong, but the function is also not tested in the adapter. This makes it basically an issue of the adapter that we also have to fix...

[`unifdef`](https://linux.die.net/man/1/unifdef) might be a handy tool in this context. It allows to easily evaluate `ifdef`s and inline or remove the code inside of the `ifdef`-branch. Use-cases I have in mind:...

I (unintentionally) reproduced the problem on my Ubuntu 20.04 system. After a lot of very messy back and forth I think I got things working now. The solution is similar...
