UDF and turbulence
Hi everyone.

I'm VERY new to UDF programming so this might be a rather stupid question for the experienced.

Anyway, here it is:

Is it possible to modify the C_mu value of the k-epsilon models with a UDF? If so, how is it done? I'm trying to make the C_mu value a function of local turbulence properties.

Thanks.. :)

Re: UDF and turbulence
I suppose You can't do it directly, but You could modify a Turbulent Viscosity (Fluent 6) and than You can set inside what You want (coefficients, function of arbitrary form etc).
