A multi-region mesh was assigned

Hi,

I am trying to create a simulation on CFD external mode but I get this message:

A multi-region mesh was assigned - this analysis-type requires a single-region mesh.

Can anybody help as I do not understand what to do?
Cheers

Hi, this is Fillia
Your screenshot shows only part of the geometry tree, but I can see that the model consists of five regions (parts). It is important that you use only one region for the incompressible analysis, which represents the fluid. Can you send me a link to your project so I can have a look?
Best regards,
Fillia

Hi,
sorry I thought I had attached it.

Cheers

The "ojoquefunciona" model consists of a flow region (solid 2), but there are also a few unnecessary parts. I suggest you delete these in your CAD software, and then re-import them, as you only need solid 2 .

Yes, I have seen that. I have already modified it in my CAD tool.
I Hope it works

Cheers!
