how could i define a custom turbulence model

FredPacheo

Dear all:

In fluent, some subroutines could be adopted by users to define a new turbulence model, such as define_source, define_diffusivity, define_viscosity and so on.And meanwhile turbulence model should be unselected.

As an example, if I wanna define a standard k-e turbulence model, two source terms should be given by define_source to define tke and epsilon. Also two uds should be involed in the solving equations.

Then my question is: in that situation as I refered, I could define a velocity inlet profile by define_profile, but as the tke and epsilon equations are unselected, how could I give the initial profiles of tke and epsilon defined by uds?
