There are three files in that folder: CAERep.xml, CAERepOutput.xml and MatML.xml. No “error” file per se. These three seem to be about input parameters and it would take a lot of space to paste all three here.

I should also point out that when I don’t specify output (like strains and deformations etc), the analysis completes normally – but again, no solver output shown. It’s just when I request such output that I get these errors.
