baseball trouble

Hi all, Some of you may have been following my troubles, curious what else you have to say. I am continuing to pursue the solution to my baseball problem, however I cannot seem to make the flow actually flow around the ball, it seems to go straight through it, the ball has no effect on the field flow. I have defined the ball with a wall boundary condition, and everything that I am doing makes sense. My duct is 120x60x60, my ball has radius 2. Velocity inlet is 20m/s and I use air, ideal gas as the fluid. Pressure at the pressure outlet is zero. In addition, I occasionally (not always) get the following error: Error: divergence detected in AMG solver: temperature Error Object: () I realize I am a beginner at this, however, I really don't think this should be this hard. I use the default solver settings with Spalart-Almaras viscousity, nothing special. Any advice for a novice would be appreciated.
