Default Drag convergence >100 (urgent)
Posts: n/a
Hi everyone, I'm doing a investigation on the drag of a ahmed body. I created the mesh with Tet/Hybrid and T.Grid configuration with spacing of 100. There is no boundary layer attached and no size function. With this I run simulation in Fluent using all the turbulence models available, with velocity inlet @ 40m/s but the value of drag is way too high >100 when it's suppose to be around 0.2. Pls advice. Thanks

Please check your reference area used for the calculation of the drag. This can be found in the Report menu, and click reference values...

Hope that helps.
