Hi again -
These forums are of great help. Thanks to everyone.
I have noticed in many thread replies, particularly those from Glenn Horrocks, that a "sensitivity analysis" is a good way to ensure the accuracy of the mesh, timesteps, and various other parameters.
I have read all of the Help file topics regarding sensitivity analyses. Although it is mentioned often with regards to finding good values for various parameters, I cannot seem to find a detailed explanation of what a sensitivity analysis is or how it is done.
Additionally to the Help file, I have searched these forums and other online resources extensively to find good examples of sensitivity analyses/checks.
I have determined that a sensitivity analysis involves the following (this is the extent of my knowledge):

One of these days I will write a FAQ on sensitivity analysis. Won't be for a while things are a bit busy at the moment. In the meantime "Computational Fluid Dynamics" by Roache is the classic reference on CFD accuracy. The JFE editorial policy on CFD results is based on Roache's work and is a good summary - http://journaltool.asme.org/Template...umAccuracy.pdf
