1. Figures 25 and 26 contain drag and residual history for the optimized solution. The drag coefficient is fully converged by50000 iterations. Residualsoscillated up until 15000 iterations before settling into asmooth trend. The turbulence residuals, ω and k, remain nearly constant from 15000 to 40000 iterations before decreasing throughout the next 20000 iterations. The drag coefficient appears to have a strong dependence on the continuity residual as both changevery little after 15000 iterations.
