I'm sorry if this is a stupid question.

In a case,I want to get the loads at some special nodes.
My global coordinate is Z-Axis vertical.
Part of my piping model is cosX=0.809 cosY=-0.588 cosZ=0

In CII guide, it's said that user can use 'right hand rule' to determine local coordinate.
In global element force report, the node loads is:
FX -416 FY -1152 FZ 2093

In local element force report, the loads is:
Fx 341 Fy 1176 Fz -2093

I can understand this. But it does not comply with the CII guide.
This is trouble to me. Because when I use 'right hand rule', y-axis in local coordinate is vertical and z-axis is horizonal.

FZ in global coordinate should be equivalent to Fy in local coordinate.

Why FZ=Fz ????

Thanks in advance.

Why is this troubling? Forget local "y" and "z" for a second, let's discuss local "x". Depending on the orientation of the element, local "x" could be aligned with global "X", global "Y", or global "Z". Therefore it follows that local "y" and local "z" can similarly be aligned with any of the three global axes.

You state you want the loads at some special nodes. If these nodes are restraints, just use the "Local Restraint Report".

Thanks for your reply so soon.

You are right. However, I possibly do not describe my trouble clearly.
I think my question is: what is the right coordinate in 'local element force'report? or how to determine the coordinate in local report?

In CII guide, the answer is 'right hand rule'. But in my case there are something different.

Maybe I have some misunderstanding, Could you direct me in this issue?

The right-hand rule always applies. Internally, CAESAR II works with "Y up", what you see (when you switch to "Z up") is a simple display switch - we don't really change anything. So, the same rules and procedures as outlined in the Technical Reference Manual still apply.
