Differences between omega equation in OF 1.6-ext and CFX 13.0
 

Hello,

I am going to use the steady CFX 13.0 solution as initialisation in OF 1.6-ext. How can I transorm the values of "omega" (OF and CFX use different euqations to calculate omega).
So does anybody now the constant factor, which allows you to convert between the two programs?

Thaks in advance.

Regards

Hallo,

what do you mean by "different omega values". Could you precise and for what application do you need it?

The difference in the omega equation come probably from the version of the k omega sst model that is implemented in OF and CFX. OF uses the version from 2003 (look at the bottom for SST-2003 http://turbmodels.larc.nasa.gov/sst.html). I don't know which version is used by CFX. The result should be similar and a constant factor cannot exist.
