Hi guys,
The curve of mesh sensitivity test, i.e. a classical variable VS # of node, does it matter if the curve is increasing or decreasing to a constant value? As long as the slope become smaller and smaller, the trend can either increase or decrease, am I right? Thanks |

Hi,
You can approach the asymptote from above or below, it does not matter. Some references on CFD accuracy: http://journaltool.asme.org/Template...umAccuracy.pdf "Computational Fluid Dynamics" by Roache Glenn Horrocks |
