Measuring relative rotation of node - ANSYS WorkBench

[Sirsh]

Hi all,

I have a rather trivial issue I am trying to solve, but it seems like there isn't anything available online that I can find to help me.

For this question, imagine I have a 2D annulus with a fixed inner ring and frictionless outer ring. I apply a moment to the outer ring and create distortion in the annulus.

What I want to find is the rotation of any element on the outer ring with respect to the centre of the annulus or any node on the fixed ring in the centre. Is this possible to do in WorkBench? As my only idea was to possible manually ID the nodes and then output the positions over time, but I'm not too sure how to do this as yet.

Any help would be appreciated!

Hi there,

Thank you for reaching out with your question. I have experience with using WorkBench for various simulations and analyses. From my understanding of your question, it seems like you are looking for a way to track the rotation of an element on the outer ring of your 2D annulus.

Firstly, I would recommend checking the user manual or support forum for WorkBench to see if there are any specific tools or features that can help with this task. If you are unable to find a solution within WorkBench, there are a couple of approaches you can try.

One option is to use the "probe" function in WorkBench. This allows you to select specific nodes or elements and track their displacement, rotation, and other properties over time. You can then export this data and analyze it to find the rotation of the element on the outer ring with respect to the center.

Another option is to use a scripting language like Python to automate the process of identifying nodes and tracking their rotation. This may be a more efficient approach if you have a large number of nodes to track.

I hope this helps and that you are able to find a solution that works for you. If you have any further questions, please don't hesitate to ask. Best of luck with your analysis!
