Modified e transport equation in k-e model
 

Hello everybody,

I am trying to set a modified transport equation for e (Turbulence dissipation rate) in the k-e model using Fluent 6.3.

1st- Is it possible ?
2nd- If yes, I suppose with a UDF. But I do not know at all how to proceed?

I can give further details about the modification and its purpose.

Thanks.
