Flow around a 3D car

How do you calculate boundary layer thickness over a 3D car in ANSYS Fluent? How do you show the limiting streamlines around the car?

    Streamlines = Pathlines and they're available in the post processing. You may need to create a line/surface to release them from somewhere upstream of the car. 

    For near wall cells, work out the cell height based on air speed and then review adaption. Note, you'll struggle to do this within the 512k cells available on the Student licence so you may need to look at half a car or 2d.
