How do I properly prepare my fan in the CAD tool for a simulation with a rotatingzone !?

Hi everyone, I want to simulate my fan in an incomperssible simulation but because I have a rotating zone I get the error

“A setup with 2 regions is being used in a single-region analysis type. Please make sure that all regions except for one have an Advanced Concept assigned to them.”

Now my question is what do I have to do in the CAD tool in order not to get this error message and how?
It would be ideal if someone would import my project into their workbench to prperate it correctly to show me what I did wrong that would be the best option for me

Thank you in advance :smiley:

here is a link to my project!


Have you already checked this article? It shows the steps/logic of the CAD preparation, with two examples: How to Prepare the CAD for Simulating Rotating Zones | SimScale


Thanks, I finally made it :smiley:
