ANSYS help modelling a ceiling fan

ANSYS help modelling a ceiling fan

ANSYS help modelling a ceiling fan

(OP)
Hi,

I am currently modelling a room with a circular space above in the ceiling, as of a ceiling fan. I have a problem with the simulation, I created a rectangular box and (it needs to be a thin wall room) with an extrude inwards of a circular cylinder, for the fan. The room is add material and the fan a frozen extrude. But when I try to do the setup it does not allow me to get a answer. I put the wall and ceiling as wall with isothermal solution. The exhaust is in the wall to let a pressure out to not blow the room up.

Then the interface of the circular ceiling fan space in the room is not rotating but is need to be put in a pressure and flow rate curve of a fan.

ANSYS CFX is telling me that I have same boundary conditions of the space and I do not know how to change the default domain.

need any help I can get, thanks, michelle
