Help on simulation domain

Hi all,
Now I am going to model following problem: A hopper is fully loaded with small sands. The sands will flow download, go through the hopper orifice and finally fall into a tank below the hopper. The simulation will stop after all sands have flowed out of the hopper. The main result I hope to obtain is the mass flow rate through thre hopper orifice. Now my question is: Shall my simulation domain only include the hopper itself, or include both the hopper and the tank? If I use the former, the sand mass in my domain will be less and less. If I use the later, the mass in the domain will be constant. I prefer to use the former choice, but I am not sure whether it is correct. Can you give me some advice on using which domain? Your help is greatly appreciated. -Derek |

Derek,
I don't see any problems with your preferreed option. I do something similar with detrermining concentration of gases over time. -Leon |

I confirm Leon Mills' view. Your simulation is similar to water running out of a tank. You should be able to simulate the hopper itself.
