Free Stream BC
 

Dear All,

I am trying to simulate wind over a truck.
I set up the truck in a middle of a box.
MY BC are
Freestream for Top,Left,Right,Front, and Back side of the box.
Symmetry plane for the Ground.
Wall for the Truck.

and for the physic model im using:
3D, steady, constant density, coupled, k-omega

I got this error:
Type "star.common.FreeStreamBoundary" of boundary "FreeStream.Front" is incompatible with available models.

Is it because Im using constant density models ?

Thank you,
Erik
