Hello!
I am use comsol 4.3a , and use the non-isothermal flow physics to simulate the heater in the room.
And the room has a door , and I want to set the door is open, and it is connect to the enviroment. So the heat and air can go out through the opened door , also the air from enviroment can supply the room by the opened door.
So I select the open boundary to the door (I don not know it is correct or not correct),
1.if the heater is remove, the simulation can sucessful, but when I see the velocity field , the result the opened door have a very high velocity inlet to the room, and it is not resonable.
2.When the room has heater,and the simulation will fail , and the result is not convergence.
So anyone know how to set the open boundary for open door?
