Dear Julio,

I have not worked with subroutines, so canīt tell if there is something wrong or not or give any advice.
It seems to me that you are using it to estimate the mean and flucting...

Another method which is more direct

There is a second direct method with which there are no arguments.
Create a 2D plane (2d plane instead of 3d to reduce amount of data and offcourse size of the files) in your geometry and extract...

"By "average of", did you mean "filtered"?"

By average of i meant average or mean.

If you have access to the data at each time-setp, then you can do a average by yourself.. it should be easy....

Hello Lance,

Yes, the equations are st out of the book by Pope and it helped me in understanding how and why k for LES = 1/2 * (Velocity.Trnrms^2 -Velocity.Trnavg^2)

or = 1/2 * (statistics...

Here is a detailed explanation

In order to find the energy dissipation rate, it is essential to understand the way in which kinetic energy is transferred between the filtered velocity field and the residual motions. The filtered...

after lot of serach, a very easy method was found through CFX help files.
they state that turbulent kinetic energy for LES = 1/2 * (Velocity.Trnrms^2 -Velocity.Trnavg^2)

or = 1/2 * (statistics...

How to obtain turbulent kinetic energy data from LES model of Ansys CFX?

Results files are obtained after simulating Stirred tank reactor and i would like to know the predictions of turbulence kinetic energy of the LES Smagorinsky model in the Ansys CFX 11. I can't find a...
