Simulation error

Project Support

Hello, I have made the internal flow thanks to help of @kaany, but I met another issues as shown in the attached file. I need my air to flow from the inner fluid volume (internal pipe) to the outer fluid volume (outer pipe), and I chose flow region because my air of the device going through like that. But the warning sign blocks me to simulate with the two flow region, therefore please help me how I can simulate with the given settings.
(I hope help of Kaany again, because he knows the fluid flow direction of this project)

*This is 1013 Case1 project in my folder :slight_smile:

Thanks again!
Best, Kim

Hello, glad to see that you’ve successfully created the flow domains. I guess the only thing missing is the 7th step I described on the other post.

“7. Use Boolen/Unite operation to form only one fluid domain. Two fluid domains connect eachother at the end of the inner pipe.”

You should also unite these two fluid domains by using the boolen operation in the CAD mode. You should have only one fluid domain for a successful incompressible flow simulation.

Hope this helps.

Thanks a lot!
