changing of k-e model
 

Hi every one

I want to use the standard k-e model with the anisotropic model of Bergeles. In this model in order to account for the anisotropy of the turbulent exchange processes in these flows, Bergeles et al. proposed to substitute the eddy-viscosity appearing in the lateral components of the Reynolds stresses and scalar fluxes by an increased value. So I have to change the standard k-e model. How can I do this in PHOENICS? I'd be grateful if you help me.
