I am trying to create a simple coordinate system on top of a cbar element so I can plot my loads in FEMAP that will match up to the results shown in my f06 file. See attached figure. I have looked into Model>CSYS but it is a little confusing for me when I have only the beam and two nodes to work with. Thanks for any help in advance.
Additionally, can anyone direct me to the location with the user manual or QRG for NX Nastran that explains how the forces from cbar elements are calculated?? I remember it's something like Force=K(B,dis-A,dis) but can't recall.
I usually use XY Axes. [Origin + 2 Vectors = CYS]. To understand the others, press F1 when the dialog box is open
Recall that FEMAP has several methods to enter vectors
Info on explaining the vector data entry in in the help file...User Interface...4.3.3 Vector Definition
I don't quite undestand your second question. I know the Element reference is found by...Help...NASTRAN NX...Element Reference
