Hi @igaviano , thank you for your quick reply.
Here is the URL to my project:
Please see the attached screenshot for the latest error code. The mesh simulation ran for 90 minutes before the error occurred.
I have ensured that all bodies are properly closed (watertight) before exporting.
Regarding the rotating zones, after reviewing the documentation, I understood that in my case, I need to use cylinders to define the rotating zones. These should remain in the flow region and should not be removed during the initial setup.
I appreciate your help and look forward to your guidance!
Cheers,
Robert
