regarding solid continuum...
Im modelling conjugate heat transfer in a contracting duct, with small annular disc-like volumes fixed inside the contracting duct(modelling a hair-dryer actaully). The disc-like volumes are the heat sources and im required to put in volumetric heat generation in the discs. I created this model in GAMBIT...and defined the discs as solids and the rest of the volume as fluid(air). After iterating, i realise that my temeprature are heating really high..around 2800K!..which is impossible as the material im using is aluminium..Im told it should only go up to around a few 100K. Wht should i do to decrease the amount of temperature? Do i have to define the solids as wall instead? Cos i read from Gambit tutorials tht defining them as solid, only enables conduction inside the solid...no convection. Plz help...

I think the problem you met in your case is due to the non-conformal mesh you may have generated. Please read the Fluent online help about conformal/non-conformal mesh.
