You can change the minimum allowable wall thickness (reduce it) and not as many cells should be limited. Does it cause you a problem or does your simulation still converge?

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...
