flow simulation / time dependent

Hi,

I would like to simulate the heating of my product. There is a fan (fluid = air) and a heat source (10kw). Some cavities in my model are filled with water at T°=5°C and their temperature is supposed to increase...

I could run a stationary analysis. But when I activate the "time dependent" option, my calculation takes a lot of time (10 mn for 1s of physical time).

Can anyone tell me what numerical method is bein g used here? My goals are useless when I'm in time dependent method, right?
Is it an explicit method? if yes can I change the time step? Any autostepping?

Thanks in advance
Loïc
