Hi everybody; I am studying now with a no-frost refrigerator thermal simulation.the freezer and the refrigerator compartments are evaluated separately.I think having a convergence problem for the analysis of refrigerator compartment.I assume the conditions are steady state and having the mixed convection conditions.analysis type option was chosen as steady state natural convection option was enabled and forced convection also.RMS level=10^-4.but the rms values has not been converged yet.I have still seen the oscillation at the rms chart for the conservation equations.

Could you advise something about it?

thanks everybody!
