Reason of leaving veocity vectors from domain

What is the reasons of going out velocity vectors from the computational domain as shown in the attached image

The length of the arrow represents the magnitude of the velocity.

The base of the arrow represents the location INSIDE the fluid domain.

As far as I can tell all those arrows have there bases INSIDE the fluid domain. Those vectors seem fine to me.

It does not look converged to me. A unconverged solution will have all sorts of weird stuff in it.

you could also just make those arrows shorter. Then you will clearly see where they are originated.

the result was converged with (10^-4 residual) but that location is jump where air with water are mixed at the end.
