changing the output coordinate system for CQUAD4

changing the output coordinate system for CQUAD4

changing the output coordinate system for CQUAD4

Hi everybody,

I am working with NASTRAN and I have a problem.

When I use CQUAD4 elements, the stresses are given in the element reference system. That reference system is computed by NASTRAN using the element diagonal bisector method. Basically, the x-axis is between the node2 and node3 of the element. Usually that coordinate system is not the one you want your output printed in.

The question is, is there any way to get the output printed (*.f06 file) in the coordinate system you want?

I have already tried using the material angle and in that way I can transform all my output in that coordinate system using a post processing code but I'd like to have the stress printed in the *.f06 file in the coordinate system I want.
I also tried using the OUTRCV command but that command works only with p-element and that is not my case, then it does not work.
Hope somebody can help me out.
Many thanks in advance.

Kind regards,
