This is difficult to understand why you are facing the issue without a file. Moreover Ansys employees are not allowed to handle any external files or link. 

Regarding your second question, yes, we can disregard other bodies and focus solely on the enclosure. The area occupied by the car can be assumed as a void, which is a standard practice for external aerodynamic simulations.


Thank you!
