cfDesign wind tunnel
 
Can i know how to make a wind tunnel test using cfDesign? i have already make a car model using solid edge, a in-depth guide is preferable since i have almost none CFD knowledge, thanks in advance.

Re: cfDesign wind tunnel
 
Kit, First you need a fluid mesh, for which you may substrat the existing car volume from wind tunnel volume and then mesh it. provide finer mesh near to the car boundary surface. with a Y+ value preferably <5. Boundary conditions: known mass flow rate at inlet; pressure boundary condition (ambient)at outlet. hope this is enough for you to start with.
