Hey guys,

I'm performing a Steady state analysis with SST turbulence model on a vehicle at 120 Km/h.

Any recommendations about the surface meshing size and the boundary layer meshing?

How many layers and growth rate should I use. I'm using a full size model with around 4m front to back, what element size should I use on the surface and in the first layer of the boundary layer?

I'm using symmetry to save computational time and only need the mesh to be fine enough so I can accurately calculate aerodynamic forces in the model.

I have tried to run several times with a coarser mesh but I'm getting a Cd of around 0.15 what, for this model seems low.

Thanks guys!
