hi
my problem is simulating a tunnel in room.it has a door in room;a cube as tunnel and in tunnel outlet is a fan;and a window in room that fan is in window too.
my desire is conditions in tunnel inlet and in tunnel and room.
my boundary conditions is velocity inlet in fan(-10 m/s) and pressure inlet in door(gauge total pressure= 0)
but now velocity inlet in door and room become 0 and maximum velocity in tunnel is 190 m/s !!!
now what i do?please help me

Hello Ahmad, I am sorry I dont have reply to your question, rather, I thing that with the model you are working, you can help me in preparing a sketch/model of a rectangular enclosure for ventilation analysis. I want to create a room having an internal heat source and with inlet & outlet doors? Please help me in developing my model.
