I'd like to use Q-Zeta turbul
I'd like to use Q-Zeta turbulence model instead of k-epsilon.But I don't know how to do this.
Once I simply replaced "k" with "Q" and "Zeta" with "epsilon" in "fvshcemes" and set turbulence model to Q-Zeta in turbulenceproperties dictionary but it did not work.
Generally if someone wants to change turbulence model,what steps are required.
I appreciate any help in steps.
Any suggestions please.
Hi Mojtaba, first you have to
first you have to select the chosen turbulence model on the turbulencePropertiesDict in constant/turbulenceProperties file. Remember to also set the right values for the coefficients in the turbulenceModelCoeffsSubDict. For your model simply define dimensionedScalar Cmu,C1,C2,alphaZ and a switch anisotropic.
Second you have to set up the proper fields needed by the model in the startTime directory (k and epsilon for kEpsilon, k and omega for kOmegaSST etc etc) with the proper boundary conditions. For the QZeta model you just need k and epsilon (have a look at the code in src/turbulenceModel/incompressible/QZeta).
Hope this is clear,
Hi Cosimo Thank you for help
Thank you for help
I'll do so.
