Default Residual oscillations - How to stop?

Hello,

I am running simulations for external flow around a vehicle for grids of up to 5 millions cells. All the residuals do converge to a nice flat plateau after 3000 iterations but there are not insignificant oscillations present.

I have relaxed the solution but I can seem to dampen them out, any ideas? The worst residual is epsilon for the realizable k-epsilon model and I am worried that my solutions are flawed.

Any helps would be greatly appreciated.

Carlos.
