12.22.3 Convergence

The suggestions below are provided to help you enhance convergence for turbulent flow calculations:

Note that when you use the enhanced wall treatment, you may sometimes find during the calculation that the residual for $\epsilon$ is reported to be zero. This happens when your flow is such that Re $_y$ is less than 200 in the entire flow domain, and $\epsilon$ is obtained from the algebraic formula (Equation  12.10-25) instead of from its transport equation.
