Support for non-SM UFO models: code generation fails in model EWdim6

[zeniheisser]

Generic issue: processes in non-SM models are not always supported (see also #614 )

Specific issue: non-SM UFO models lack support, even outputting more exotic models (eg EWdim6)

import model EWdim6
generate u d~ > w+ z
output standalone_cudacpp

Hi @zeniheisser thanks a lot. We clearly have a lot of work to do :-) I would keep this one at very low priority for the moment - unless you tell me this is precisely one of the most interesting examples, eg for your work on reweighting and/or with Robert...

[zeniheisser]

@valassi, this one doesn't matter (to me at least), but #614 is about the model that they use in the Vienna group, so I'm going to look into that one at least

accidentally closed the issue

Hi @zeniheisser as discussed, it turns out that my recent patches for SUSY, HEFT and SMEFT fixed code generation for the process you suggested. So this #615 is fixed and can be closed.

I added more tests in PR #847. Note that the code builds and runs, but there are some wrong results (see #846) to be fixed.

Closing.
