External flow failure

My project is to make rotational flow simulation over a certain fan geometry.
The external flow has been failed, and I do not know the reason.

Please help me. :slight_smile:

Best, Kim

Hey Kim! I believe this issue is already solved on your side, I see that you were able to generate the external flow region. Do you need further support on this?
