Fluctuations in teh Residual graph
 
Hi,
Can anyone tell me what does the fluctuations in the residuals graph mean ?
I am using turbulence k-epsilon model with energy equation. residuals of continuity, energy and k seems good but x velocuty, y velocity and epsilon residuals are fluctuating and fluctuation of epsilon is significantly higher than other ones.
Thanks.
