Inconsistencies in structure of tutorials

[MakisH]

Follow-up of #228. The structure is documented in the website and clarified in precice/precice.github.io#331.

The following tutorials need updates:

• oscillator @uekerman
  • python
  • fmi
• partitioned-heat-conduction
  • fenics: Follow naming convention in partitioned heat conduction - FEniCS #459
  • fenicsx (move from develop to branch) @IshaanDesai
  • nutils @uekerman @IshaanDesai Fix inconsistenies in the Nutils participants of the partitioned-heat-conduction tutorial #496
• partitioned-heat-conduction-complex
  • fenics
• partitioned-heat-conduction-direct @uekerman @Fujikawas
  • nutils
• volume-coupled-diffusion @BenjaminRodenberg
  • fenics Fix structure of volume-coupled-diffusion #489

I would still consider the aste-turbine to be a very special case that is not meant to be extended or repeated in other tutorials.

Please comment regarding which cases you would like to port. No need to port every tutorial at once, but let's try to have a consistent structure until the next release of the tutorials.

I don't want to prioritize this before my thesis is submitted or at least close to submission. I think this is also something that could be easily done by a research assistant and not urgent.

[MakisH]

You mean that you don't want to work on it now, or that you don't want that the structure changes now?

[BenjaminRodenberg]

I'm fine with the structural changes and we can also implement them rather sooner than later, but I don't have time to do it myself now.

If I stumble across a point where I can briefly do it anyway, I will do it occasionally (e.g. 459ab90).

[MakisH]

Thank you, I can also take over work packages on this.

Please don't update the oscillator before merging #466
