Hello, I'm studying the Rigid Dynamics Capabilities of ANSYS and, in particular, how joints work in Rigid Multi Body Simulations.

Reading the ANSYS Mechanical Rigid Body Dynamics Course, Module 3 (Connections/Joints) I came across this slide:

I don't understand what to do in order to have an associative Coordinate system and why it is recommended that all reference CSs be defined as associative.

Sometimes it happens that more than one Reference Coordinate system has an axis defined "by default", but I don't receive any warning about the fact that I'm working on a non-fully associative coordinate System.

Thank you so much for any explanation you will provide me with!

Please do not post images of Ansys course material online - we have removed this screenshot now, but please be aware of this.

I would strongly recommend to ask this question in the ansys learning hub since you can then refer to these points in the slides and the instructors who have developed these (slides/notes) can then hopefully comment on the points you ask in your post above.

All the best

Erik

Dear Erik Please excuse me for the screenshot I attached to my post.
I'll contact the Learning Hub according to your advice.

No worries at all.

Sure the instructors (Ansys Learning Hub) will be able to provide some good feedback with regards to your questions.

All the best for now

Erik
