Can't get my CAD file meshed on a thermal comfort CFD simulation

Hello, I want to have a convective simulation but the mesh fails. I have followed almost all steps (i think) from this video. Simulating Thermal Comfort In a Ventilated Office Space | SimScale Tutorial - YouTube

I need help on preparing the model, I am not sure if it needs to be solid or hollow with the ducting.

Cheers!

Hi there, have you considered using the standard meshing algorithm instead? It is reliable, and here you can see the results without any refinements (or flow volume extraction for your case):

It was finished in 2 minutes. Of course you can increase the fineness level and even add some refinements in critical areas, especially if you create a new simulation and divergence appears.

Let me know what you think!
