Initialize volume temperature field with a computed field

magnounibo · December 10, 2009, 03:54

Hi everybody, I got a question about Fluent initialization: I would like to initialize temperature field in a volume with a solution computed in a past run. I necessarily have to reinitialize all the fields for a new simulation, but I would like temperature not to be reinitialized.
Can anybody help me???

Thank in advance

Patch all other parameter but temperature.

I understand, but I got a problem: I have to perform a two-phase simulation, starting from single-phase temperature field. To initialize volume fraction, I need to use a DEFINE_INIT UDF, which I think need also a GUI inizialization. So I think a have to initialize from GUI, losing my old temperature field.
