Quick question RE: UDF

August 22, 2007, 11:20

Hello all,

Thanks in advance for your time and help. I wanted to implement a variable energy source in a solid zone in FLUENT. That is to say, I want the energy generated in a volume to be X W/m^3 for some time, then change to Y W/m^3 for some time, in a transient analysis. I haven't used FLUENT and UDF's before, can someone tell me if this is possible? I am reading the UDF manual now, but was hoping someone could help me.

Thanks, Dylan

The SOURCE example in the UDF manual covers this.

Alright, thanks. I haven't gotten that far into the manual yet.
