Default Dissipation rate access

Posts: n/a
Does anyone know what the 'Specific Dissipation Rate' is that Fluent is defining in the macro:


I am using a k-epsilon model, I am wondering if I can get direct access to through macros

1. The turbulent kinetic energy dissipation rate

2. The viscous dissipation rate

I know how to access the turbulent kinetic energy dissipation rate, that is simply C_D(c,t). What about the viscous dissipation. Does Fluent allow access to it? Is it even possible with the k-epsilon model to decompose the output dissipation to the turbulent and viscous dissipation so that one can compare their relevent magnitudes? Thanks
