I'm hoping someone can give me some help getting this solution to converge.
I'm using k-e with non-equilib. walls, velocity-inlet and pressure-outlet. The velocity is at a lowish 26m/s for now, but I'd like to bump it up later.

I can't seem to get any convergence with the default fluent relaxation factors or the suggested factors if your solution diverges. Using:
pressure=.2
mom, k, e=.5
I can get a solution that just kind of flat-lines instead of wildly diverging.

Right now turb. intensity is constant over the inlet and outlet. Should I stick with those?
I get lots of turbulent viscosity ratio limited messages during the solution. I read in a few other threads that shutting off momentum for a little while and iterating can help solve this, but it doesn't seem to help.
I should not that, right now, the car has no wheels at all. I wanted to take this one step at a time.
I don't have a boundary layer on the ground.
I've heard taking a looksee at the velocity vectors can tell you where your mesh may not be good, but I can't get a solution converged enough to plot any vectors.

Any help?
