does anyone know what does flowType do?
i used flowType command.how can find type of flow(shear flow,with or without circulation or fully turbulent mentioned somewhere i saw) from the numbers like:
Code:
0.07651246272745461 |
nobody knows?

Hi Immortality,
In the Doxygen C++ documentation you will find the following explanation for flowType: Description Calculates and writes the flowType of velocity field U. The flow type parameter is obtained according to the following equation: lambda = (|D| - |Omega|)/(|D| + |Omega|) -1 = rotational flow 0 = simple shear flow 1 = planar extensional flow I don't know the exact meaning of D and Omega, but it seems that D is a measure of the angular deformation of the fluid particle and Omega is a measure of it's rotation.

thanks.I has saw that.but what does .37 mean it not exactly 0,-1,1 ?
is this somewhat like 0 and somewhat like 1 propounded numbers? |
what's the usage of it?does it have an equivalent parameter in CFD?has anyone encountered it in CFD texts anywhere?

have you ever found out about what would be the usage of "flowType"?:confused: I mean what's the benefit of this command? Best, Mehdi. |
