frame of reference

Hello dear community, I wanted to ask you if you know in which reference frame Code-Aster performs the calculations, it will be in the co-rotational system? how can I know this? I have seen that through the command AFFE_CARA_ELEM is possible to assign a local reference frame, but I need to be 100% sure of what are the calculations it performs, ie, if it rotates first and then translates, or if it translates first and then rotates, etc..
I hope you can help me, best regards.
