Im doing steady state 3D simulation of a centrifugal pump using impeller geometry generated using BladeGen with data given by Vista CPD for some particular operating conditions. The volute geometry was also based off Vista CPD data. CFX was used to setup the simulation. Assuming that the setup(boundary conditions, interface def, solver settings etc) was correctly done, is the following streamline plot correct for starting points at the rotor inlet?

Why are continuous streamlines starting from the rotor inlet and reaching the stator outlet not observed?

PS. Convergence was not reached, around 200 iterations were performed.
