Hi @ChipQuick, thanks for posting.
I think a first point would be that the generation of the flow volume is completely necessary - you need to go through this step before moving on with your setup.
A second point would be that, as we usually advise users, it’s better to start simple and build on complexity as you go. E.g.
- Defeature your initial geometry to the most absolutely simple shapes
- Generate a flow region
- Understand how the boundary conditions work
- Generate a mesh
- Run a basic first simulation
Once you’re comfortable with that, move on to the more complex stuff such as humidity modelling. Our users find the introductory tutorials very helpful to give them these first steps!
Cheers
Igor
