January 17, 2011, 04:14	Negative velocity profile	#1
siddharameshwara Member Join Date: Sep 2010 Posts: 36 Rep Power: 16	Hello, I am simulating diesel flow in the nozzle of injector in OpenFoam. The velocity outlet boundary condition for nozzle is inletOutlet uniform (0 0 0) m/s . But , i am getting negative velocity at the outlet. Actually it should be positive(Diesel flow outside of the nozzle) or zero.Could any body tell me why !!negative velocity !!! ?....any reasons???do i need to change my boundary condition. Thank you in advance.
