Cannot reproduce reference results for elastic-tube-1d fluid_cpp - solid_python about tutorials

I opened a more detailed issue in precice/precice#1984.

An interesting observation, which is probably worth checking even before getting into fieldcompare is that the iterations differ in both cases.

I understand that this issue has two parts:

• the "getting different results between v3.0.0 and develop" has been addressed in precice/precice#1984
• the "getting different results locally than on GitHub runners" is partially not an issue, partially covered by #393.

Closing as duplicate.

Sounds like an instance of #393

Alright, so I wait for the bug investigation in preCICE before looking deeper into this from the perspective of the system tests.

My last comment is a bit off topic.

I cannot reproduce the reference results locally (this issue) and the precice develop produces different results than my local v3.0.0 results (linked issue).

Well, every system is expected to give a bit different results, hence the selection of the tolerance is important.

Reference results are generated on the GitHub runners with this workflow: https://github.com/precice/tutorials/actions/workflows/generate_reference_results_manual.yml
