Since i dont think you cant download the file even if i upload it here, could you help me to analyze what else could be the problem, or what other info do you  need, i can make a screenshot out of it.

i just realized i did some typo on my last reply, what i meant i ve tried to use the contacts and use the imported load but it still doesnt work.

And yeah i tried to change to the normal structural steel (which i think a linear material model) and it worked without problem.

how can i do nonconveregence diagnostics? is there any video about this?
