And the flow field & mesh?  80 iterations isn't very many; under the Residual panel "advanced options" set check convergence as off. That'll monitor the residuals but not stop the calculation when the threshold is set. A residual of 1e-7 is very small, so I'd expect a good result but I also don't like models that have run so few iterations.Â
