Problem setting regions
 

Hi, I'm trying to simulate an aircraft inside a wind tunnel.
I can import my CAD model without problem, but when I try to create new region from the parts, I'm unable to click at "Set Region"
Can you help me??

I attach a screenshot with my problem

You should assign those parts to regions first. Instead of clicking on set region, click on Assign Parts to Regions...

ok, the simulation is running
thanks :)
