HI!
I have a car Inside a box (in a volume) imported in FLUENT and would like to have the boundary conditions done,
As far as I know I am supposed to have;


Wall ------ Ground or Floor
Symmetry----------in the symmetry half of the car (the split)
Velocity_inlet--------------Front body car
Pressure_outlet---------------Rear body car
???------------------------Top
???---------------------------Other symmetry half (the other side)

SEE ATTACHED THE PICTURE


I guess I have 2 empty boundary conditions and I am not sure what they have to be I am sure one of them has to be (farfield).


THANKS!!

Assuming the two boundaries you are asking about are far enough away from the body to be "free-stream," you want a far-field pressure boundary condition there.
