I setup a model in starccm+. I get a warning "wall distance limited in n cells". I ran the simulation anyway and my solution seems to converge nicely. The residuals all decrease. I read in the manual that if you get that warning about wall distance, you should remedy it. So I tried reducing the minimum allowable wall distance so that less cells are limited. Now my turbulent residuals and energy residuals seem to be oscillating, though the other physical parameters that I'm monitoring in my solution still seem to converge correctly. So does it matter if a small number of my cells have their wall distance limited (~1,000 in a 6.5 million cell mesh)?
