Hello,
So i have a casting with pipe in mold. Thru the pipe is flowing a cooling fluid. I want to analize how many fluid is needed to cool the casting to certain temperature and how fast the cast will lose it's temperature (of course that will depend on cooling media). And i want to have a closed flow, so the temperature in container with that fluid will grow. Can i model something like that.

Yes, you can. Flow-3D has some Heat transfer models. There is also available some specifics models of advection for confined flow and you can also accelerate this kind of problems to steady state.
You can find examples in Flow-3D techpapers as well.
Hope it helps,
Dani

To model a closed system, you could employ a periodic mesh boundary condition, in which whatever leaves at one end enters at the opposite boundary. However, without an extraction of heat form the fluid in the cooling system, it will just heat up to the temperature of the casting, eventually, wouldn't it?
