I want to make a flow simulation for an UAV with the rotors rotating. When I am not choosing the rotating regions, I do not have any problems, but when I am setting the regions for rotating(making that cycliders and I am not merging them with the rotors) it appears an error. What can I do to solve the problem?
I want to specify that I am using an assembly.
You have not given us enough information to help you.
What is the error? When does it occur? What kind of rotation model are you using?
Have you used rotating regions correctly in the past, or is this your first time? They can be tricky.
