Good advice. Always start a RANS calculation with a grid independence study. Comparing profiles or resulting quantities across your domain. E.g. the pressure drop in this case or the velocity profile (not contour) at the recirculation zone.
hello, i would like to say your videos have been very beneficial to me as an aerospace engineering student. I would also like to kindly request you make a video on biconvex airfoils in supersonic flow, please.
Jorg - nice job - you could also have stayed in Fluent without go back to the ANSYS mesher and used Mesh Adaption - you can see this feature in the toolbar ribbon - you can then select the flow field with high gradient and adjust your mesh to accommodate a mower gradient in those regions where it is deemed more turbulent than laminar flow - re at your elbow - this would get you where you want to go - quicker - with less guesswork on what to do - there are other options of course - however - nice to see a first principals approach too - you might want to create another vid showing this approach for comparison

it´s better to use the region mesh adaption than the gradient one since the topology of a mesh can be preserved
