jane Guest Posts: n/a	Hi, I am trying to simulate the flow in a duct with a small fan. Since I don't care the details of the fan, I would like to simulate the fan using an axial body force in the duct at the fan.Does anyone know how to add a body force in FLUENT? Suppose I know the pressure ratio of the small fan.
