turbulent viscosity in k-e model

orlik · March 31, 2010, 12:48

Dear All.
I want modify turbulent viscosity in standard k-e model. (insteed constant C_mu=0.09 used values which are calculated in each cells)
What i already tested that i computed turbulent viscosity using UDF DEFINE_TURBULENT_VISCOSITY but i see that in results my turbulent viscosity also depend from constant c_mu.
So, i think that i have to modify c_myu (standart C_mu=0.09) in each cells, how i can do that?

Hello Orlik,

Were you able to modify CMU? Can you please tell me how did you do it.

Thanks
