@pcarruscag In this PR, I have a problem with running the regression tests, because it can not find my branch, as can be seen in the figure below:

I believe it might be related to the fact that I'm creating a PR from a created fork of the SU2 repository, instead of just having an own branch in the su2code/SU2 repository. So, the branch I'm in is located in sjhbtue/SU2. Could this indeed be the problem or do you think I can still solve it in a different way? Thanks in advance!
