Hi all,
when I am trying to run my PHAST modell (it completed runs already before, I put it aside for a few months), I get the following message:
array allocation failed: XP_init_thread
Any ideas what happened here?
Thanks,
Tamas

It usually means that you ran out of memory. See if it runs with a coarser grid.

Thank you, it was actually a problem with the number of threads set to use. Now I have a convergence problem but thats a different issue.

Its me again. I was trying to work out the convergence error on my own but no luck. Even if I run my model with only distilled water, my model won't converge. I get the following messages:

Do you have any suggestions about what to improve on? Thank you!
