Hello all,

I am conducting drag analysis using Ansys Fluent R19 Academic version.

My project is regarding analysis of drag and noise due to a sunroof cavity.

When my car model only has a sunroof cavity (without deflector), there is no problem in Boolean operation, i.e subtracting my car body from the enclosure.

But when I add a deflector at the leading edge of the cavity, the Boolean operation is failing.

I have attached pictures for your reference.

I would really appreciate it if someone could help me as my project deadline is in the very near future.
