hi all,

I am relatively new to CFD and want to ask a question about simulating engine.

I intent to simulate the flow around the aircraft using fluent. The aircraft is with engine hanging under wing. Currently I am making the engine nacelle hollow so that air can flow through it. But that does not really represent the effect of the engine as it is empty.

I was told that i could set a pressure jump in my engine nacelle using the inlet fan boundary condition. However i am not sure how exactly i need to set up this. Do i still keep the engine hollow? Where do I exactly place the boudary condition, in the front part, back part or in the middle? If i set the inlet fan condition do i still need a outlet fan boundary condition? Thanks in advance and do bear with me as i really have little experience with fluent.
