I wanted to look at how you set up air flow between internal and external air volumes, and it appears the site is down.
And while I have your attention, can I use the software to create more than one air volume, or do I have to do that in my CAD system first?
Solved! Go to Solution.
Are you still seeing an issue? I just looked now and it seems OK.
If you would like to create nested volumes for meshing (a good idea in the case of your models), it is best to do this in CAD.
