TEMPERATURE RAISE !!?
 

Hello everybody, Excuse me for my poor english...

Here is my 2D problem: there is a plane plaque name "Gado" with a ID domain =2 I want modify automatically the temperature of the plaque as :

At time t=0s , the temperature of "Gado" is 293K At time t=1s, the temperature of "Gado" increases 2K (Warning, there is a temperature gradient inside "Gado", I want all cell increases 2K, but "Gado" preserve his gradient) At time t=2s, the temperature of "Gado" decreases 2K.. ...

What kind of UDF function ( DEFINE...) I must choose for that? I am thanking you in advance for your help.
