Heat Transfer

Hi everyone,

I have a simple problem regarding heat transfer. I have a simple rectangular hollow box and want to set the box temperature say (100 [degC]) The box is filled with air. I placed a copper sheet inside a box and wants to observe that after a certain time how much the copper sheet is heated, without applying the input power, the only input power is the box set temperature (100degC), The heating source is the copper sheet. Is something like this possible in Comsol..??

Will the temperature of the copper sheet exceed to the preset box temperature (100degC) or not..??

Can someone answer me please..???

Appreciate any help..

Thanks in advance...
