calculate epsilon from RANS k-Omega simulation
in order to get the epsilon value from a RANS simulation (kOmega, kOmegaSST respectively) I was searching the source code. This is what I've found in kOmegaSST.H:
I don't know if this is the best way to get the epsilon value but it works! :)
1. create the directory ~/Openfoam/$USER-2.1.x/utilities/postProcessing/turbulence/
2. copy the attached files into.
3. run the command "wmake" from the epsilon directory
This will create the folders platforms/.../bin in the ~/Openfoam/$USER-2.1.x/ directory and compiles the epsilon.C file. The executive "epsilon" is created there and can be called by "epsilon" from any case directory.
Note: This should work for kOmega as well as for kOmegaSST. While the difference is simply a change of constants:
Which is normally the same value: betaStar=Cmu=0.09
