Hi masters,
I would like to implement a new LES model in cfx, while i dont know how to use variables. As far as we know, the normal eddy viscosity model is : mu_t=(C_s*delta)^2*S If i want to add another term (including volume fraction etc.), i suppose i need to use Default Domain>Fluid Models>Turbulence>Advanced Turbulence Control>Eddy Viscosity. Then in the expression of eddy viscosity, how can i indicate these variables, like "delta(filter width)" "Smagorinsky Constant" "filtered rate of strain tensor"? Need i implement subroutine to do this? Many thanks! |
