Inlet boundary conditions from profile data -- CFD Online Discussion Forums

April 15, 2013, 14:38	Inlet boundary conditions from profile data	#1
M_Tidswell Member Mark Join Date: Feb 2013 Location: London Posts: 33 Rep Power: 13	Dear All I have applied an inlet boundary condition from a previous simulations outlet using profile data and it looks great for the first 20mm or so however.... just after that a section of essentially stationary fluid develops for about 300mm right against the wall like a very shallow bump. This doesn't exist in the full size flow so it is developing due to the implementation of the profile data inlet condition. Has anyone else come across this? Is there any way to eliminate it? I have tried manipulating the data a bit to see if it is an issue with the velocity data but it appears not. Many thanks Mark
