I have tested my UMAT code successfully with sequential mode, which meaned ABAQUS did not use multiple CPUs.
But when I ticked using multiple CPUs, the UMAT runned into errors, which showed NAN value in print message.
I need to read same txt file every time while executing UMAT, though I tried to duplicate these files in different folders, the errors were still existed.
Besides, I also had to use STATEVs to store some values, and read them in next excuting UMAT time.
In short, what I want to do could be intepreted as reading TXT files in elastoplastic UMAT in parallel mode.
I will owe my gratitude to any help, thanks.
