Hi,
Why do the results change drastically if I increase the size of the control volume (eg. the mesh around an airfoil)? The result should improve for a bigger control volume, however in my case the results diverge. Thanks. |

Hi John,
in most cases you obtain a better result as much as fine your mesh is. Not the other way. An exception from this rule is for example spray-simulation. Christof |
