Merging Parts for External Flows
 

Hi,

I'm new to FLUENT, and I'm having the following problem. I've created a car in Rhino, and have exported it, and have loaded it in Ansys Workbench. Because I want to simulate an external flow, I am planning on using a boolean operation to subtract the car out of a larger flow field.

However, the car has lots of parts (polysurfaces, volumes, etc.), and you can't do a boolean operation on many parts (only 2). And, when I try to join the parts in the Modeler, using Merege or Connect or even Union, they don't all merge. I'm still left with lots of different pieces.

Is there any way to go around having to merge all of those pieces?

Thanks.
