the difference between FLUENT6.3 and 12.0 in heat transfer
 
Hi everyone,
I am a new comer to this forum.
And my case is about heat transfer in oven. The heat source is a heater of fixed power. The results from FLUENT6.3.26 and ANSYS12.0 are totally different.
After 20min transient calculation, the temperature of heater is about 800K in 12.0, and >1000K in 6.3.26.

I want to know the reason. Thank you!

PS: The model included one heater and a block (rubber) in the oven. I used DO radiation model. and all the settings are same. furthermore, the result from 12.0 is closer to test result.
