Meshing Error: One or more cell zones do not intersect the flow region

Project Support

Hello:

I am trying to run a simulation of a blower with a MRF Rotating Zone.
It starts meshing but I get the following error meshing message:
“One or more cell zones do not intersect the flow region or the intersection results in a non-solid body. Cell zones must overlap with the flow region.”

I tried to ind the meaning of this message but, couldn’t find anything.

I need some help to figure this one out.
My project link is:

Thank you in advance.

Hi @sbouchard,

There are a couple of CAD preparation steps missing, please refer to this documentation page for an example: How to Prepare the CAD for Simulating Rotating Zones | SimScale

Hello Ricardo:

Preparing the Rotating Zone solved the meshing issue.
Thank you.
