Negative velocity profile
 
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 :confused:negative velocity:confused: 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.
