Fluent transient Simulation - varying Internal Heat generation : Help!
 

Hello Fluent-experts,

I am trying to simulate a transient case in fluent, where i have a CHT situation. I have a heat generating body surrounded by fixed volume of air. the outer faces of air have constant temperature. Now the heat generation of the central object changes with time. I have defined my Cell-zone condition of this central object with a source-term. But I do not know how to define a time-varying internal heat generation value.

any help or tips would be greatly appreciated.
Regards,
Ram
