Hi everyone.
I want to add a function of height to the definition of turbulent viscosity in STAR-CCM+ mu_t = rho * Cmu * k^2 / epsilon * (function of height) I was recommended to change the property of density(rho), but I failed to change it. it gave an abnormal results. thank you. |

did you try changing dynamic viscosity?

I want to change a turbulent viscosity but not a dynamic viscosity

My thinking was that by changing dynamic viscosity this affects k and e, which might get you what you want, indirect way,
