HI all

i wanted to simulate a simple CHT problem.i have taken a copper plate,placed in ambient(open atmosphere) and it is heated by passing current and i measured the temperature on copper plate, now i want to simulate it in cfx,my doubt is how take surrounding air as a domain, if i create certain voulme of air around the copper plate how much volume i have to take,can i apply opening bounday condition in all the outer walls of the air domain if not what boundary conditions i should apply

Thanks in advance
