@KulaginVladimir yes also! The same principle would apply! I made a [small example](https://github.com/RemDelaporteMathurin/FESTIM/blob/anisotropy/anisotropy.ipynb) on how to achieve this in the fenicsx branch for a simple diffusion problem.

@KulaginVladimir there you go I adapted it to thermal conductivity https://github.com/RemDelaporteMathurin/FESTIM/blob/anisotropy/anisotropy_thermal.ipynb

I noticed this bug also occurs on the main branch!

💡In 2D we could tag each surface (top, bottom, left right) with an index and document it

#755 is in this direction

Hey @Allentro what is the status of this?

Hi @Allentro! Do you want someone else to pick up this PR?

The result isn't ideal as it adds the icon button in the sidebar and not the header. I opened an [issue](https://github.com/executablebooks/sphinx-book-theme/issues/833) to see if it is possible with the sphinx-book-theme
