Smagorinsky Dynamic Cosant in UDF
Hi, i'm performing some tests on the LES module of Fluent with the turbulent channel flow.
I wrote an UDF to export my data in an external file but i can't find the Dynamic Constant in the variables. That is:
C_U(c,t) is the x_velocity
C_V(c,t) is the y_velocity
C_W(c,t) is the w_velocity
what is the command for the Dynamic Constant?
If there is not such a command, do you know if the following one:
which is the turbulent viscosity, is also valid with the LES model?

If it is needed for postprocessing you can extract a dynamic constant Cd by
Cd = mu_t/(rho*SQR(delta)*S);
