continuity residual

March 6, 2002, 19:48

Hi, I'm modeling a multi phase flow of air and water around a automobile tire,2d problem.i'm using k-e ,rng tubulent model.i chose the tubulent intensity and length scale option with values 5% and .3m respectively at my inlet.(2 velocity inlets..air and water).now when i start iterating my continuity eqn goes diverging...can anybody suggest any parameter change to avoid this?thanks.Mavinakere.

I am having the same problem with my counter rotating propeller model. All the other residuals seems to be dying out except that the continuity residual keeps going up until it diverges after about 15 iterations. Does anybody have any idea how to fix this?
