Hello!

I am very new to ANSYS so I have one (probably) beginner problem.

I am trying to simulate a swinging of a pendulum and when I try to define a Revoulte Joint from Body - Body, the spinning axis is wrong - the axis should be Z but it becomes X.

Why is that and what should I do to repair this problem?

Thanks in advance.

It should pick the correct axis in general not sure why you got this - anyhow. In order to modify and do what you want:
Expand (revolute tree item) as shown and look on the ref. coordinate system as shown below - one can then modify it using the marked transform buttons (yellow marking). You would need to rotate about Y 90 degrees.
All the best

Thank you.
I have absolutely no idea, why it would rotate the coordinate system in a wrong way.
Is it possible that it's because I have imported geometry?

not sure, but at least now you know how to rotate it and resolve this :).

Thank you

[ErKo]

not sure, but at least you managed to rotate now :).

All the best
