[Daisy Duck]

Hi there. I was just running a quite big case file and after it was going just fine for about 150 iterations I started getting the message: turbulence viscosity ratio limited to 1e+005 in 1 cells....2 cells.. and the cell kept of increasing. I read a couple of similar topics but they all said that it happened in the first couple iterations and it disappeared. Anyone knows why is this happening? I tried plotting the ratio, but I can't show the contours everywhere because fluent freezes ( probably not enough memory). I did however see them on the sides of the cabinet, and the components inside. They looked just fine. So i am assuming this is happening somewhere in the fluid around it, but i can't see where. also the highest ratio on the scale was about 3.5e+4, which is not so close to 1e+5.

edit: this is about air flow over a race car. I am using Reynolds stress model(7 eqs). This is what my teammate told me to use ( i am still learning). I though k-e is the one I should have used. Can anyone tell me what is the difference?
