Hi!

I'm using the k-epsilon Turbulent model to simulate the flow over the Prolate spheroid body. But in the Residual plot, the Residual of K and Epsilon is high (between 1e-1 and 1e-2) even the Residual of Velocities and continuity is alright.

Somebody can say to me something about it? It is Ok or if not how to avoid it?

Thanks in advanced!

PAH.
