Releasing moment or force in local coordinate system

Releasing moment or force in local coordinate system

Releasing moment or force in local coordinate system

(OP)
Hi,

I have a question which is killing me. I realllllyyyyyy appreciate if you can help me.

situation and structure:
I am dealing with the structure with large movement and I am doing static and transient analysis with large displacement. I can not release the moment in global coordinates since I have large movements. Fro example if I release X-rotation, in the middle of the analysis X axis will be between original X and Y axes.

Question:
I am pretty sure that (('Preprocessor'/'coupling/ceqn'/'coupleDOFs')) works in global coordinate system.

When I am checking the results of the analysis (and also the manual) of the following joint elements

Revolute Joint (combin7)).

and

The MPC-184 general joint
http://www.kxcad.net/ansys/ANSYS/ansyshelp/Hlp_E_MPC184gen.html

It seems that the response is in global coordinate system. How I can release moment in local coordinate system?
It seems to be a very simple answer but it is getting the hell out of me.

Again,
Thanks for your help and time in advance
