Why do flow trajectory lines stop and some continue?

I am running an internal flow simulation. It has a volume flow rate inlet boundary condition, and a atmospheric pressure outlet boundary condition.

the part being modeled is a thermal head with very small and thin pin fins so the mesh is very small. The simulation runs fine, but when creating a flow trajectory plot some of the line stop before reaching the outlet and only a few reach the outlet.


Why would some of the trajectory lines suddenly stop?
