if SS and you're still getting high resids and have looked elsewhere, try unsteady.Īs for convergence, as many people have said, its not only dependant on residuals, physical values need to be monitored as well, but its also dependent on degree of accuracy you're looking for in your model. if you're using explicit unsteady, must monitor your CFL. You may also need to increase your inner iterations/decrease your timestep/ increase resolution for your mesh many different ways to do this. for this i would refer you to an article spalart wrote on the topic (tubulent boundary conditons) K-eps is sometimes sensitive to inlet turbulence conditions depeding on which version you use ( i can't remember specifics on this). depending on your turbulence model - looks like K-eps? - you may need to adjust your turbulent boundary conditions for your inlet. I've since fixed my problem with high residuals.

Using the threshold,how high does the residual need to be to be considered too high? TKE and TDR residuals both flatten out a long ways above 1.0. On my simulation, everything converges except TDR and TKE.
