Hi everyone,

This work updates the transition portion adding config and mesh files for the LM2015 model and the SA-LM coupling.

There are probably some missing files, once you add them change the target branch from master to develop

Can I upload a 3D mesh? Because it is pretty heavy. However, it is freely downloadable from a site. Should I only point it out somewhere?

Yes if it is too big link to the source

I've put a link in the config file.

You have config files both here and in the code repo, which ones are you trying to use?
If your meshes are in the tutorials repo you need to use the tutorials.py script to create the regression.
