Dear Luigi,
Thank you for your feedback. Actually, I do not know which vectors I should modify in usrsuw.f…
What kind of information you need to know to better understand the error?

Dear Fabio,

it’s not easy to debug this error with the info you provided…

According to previous messages on the list, it could be there is a problem in processing the recnuc files,
most probably because you’re running out of memory.

If this is the case, you should assign more space allocation to some vectors inside usrsuw.f (you need to compile it).

Hope this could help.
Cheers luigi
