Boundary conditions over-constrained

So, I am trying to use a 1D model input as boundary conditions for my 3D simulation.
I know the velocities at all boundaries from the 1D model, so I input them into Fluent, and left one boundary as a pressure boundary not to over-constrain the physics. However I tried changing this to a velocity BC and to my surprise the calculation started running with no error message. What is the meaning of this? Will it calculate but have some continuity imbalance? Thanks in advance!
