Add solid-mfem to flow-over-heated-plate

[j-signorelli]

This PR adds an MFEM implementation of preCICE for the flow-over-heated-plate tutorial.

Checklist

• I added a summary of any user-facing changes (compared to the last release) in the changelog-entries/<PRnumber>.md.
• If I changed requirements.txt files, I regenerated sibling requirements-reference.txt files with python3 .dev-tools/releasing/update-requirements-reference.py (pass a path to update only that directory, or --all to refresh everything).

For new tutorials or tutorial cases:

• I followed the tutorial folder structure
• I added/updated the tutorial README.md
• I added/updated the tutorial metadata.yaml
• I added tests in tests/tests.yaml
• I submitted a pull request to the website with:
  • An entry in _config.yaml
  • A sidebar entry
  • An entry in the tutorials overview

@j-signorelli nice to see this draft!

Hint on the failing CI: we use pre-commit and this also checks and adjusts the formatting of some files. After you install it, do pre-commit install and pre-commit run -a to fix the files. Read more.

We can clearly improve the contributing guidelines here (tricky among multiple repositories). Any feedback is welcome.

@MakisH gotcha, thank you!

@MakisH This is all ready for review! I don't think there are any required additions to make to the website based on what I saw - please let me know if I am mistaken. Also, I am not sure if I should put anything for components in the metadata.yaml as this doesn't involve any adapter or anything - just an in-place usage of preCICE with MFEM

@j-signorelli with a quick look, this PR already looks very clean, thank you! I will have a deeper look this week and integrate it to the system tests.

[MakisH]

I could run the new case in the system tests, and the results look as expected:

The structure looks good, and the solid.cpp file looks clean (I did not look into details). The README.md mentions the new case.

The case is not configurable (parameters are hard-coded in solid.cpp), but so are also the cases in solid-nutils and solid-dunefem.

Note: In the Dockerfile, I modified the aste stage as well. I have checked that this works.

Thanks a lot once more for this PR! I will take care of the reference results and the integration to the website.

Awesome! What would need to be incorporated to make it “configurable”? I could add in more command line options if needed if the current ones are insufficient.

[MakisH]

There are indeed quite a few command-line options. I meant having an adapter configuration file, similar to https://github.com/precice/tutorials/blob/develop/flow-over-heated-plate/solid-fenics/precice-adapter-config.json

We now have an adapter configuration schema, which is still under development and evaluation: https://github.com/precice/adapter-schema In the future, we want to make all adapters (including such solvers provided in tutorials) conform to that schema. But that will still take a while.

P.S.: The tutorial is now also on the website https://precice.org/tutorials-flow-over-heated-plate.html
