Question Shear stress induced on fluid in centrifugal pump

MechKim is on a distinguished road

Im completing a study on an artificial heart pump. I have completed a CFD model in CFX, however i am confused as to how to determine the shear stress induced on the blood. Predefined expressions gives Wall Shear Stress, but i dont think this is what i need.
Do i need to define my own expression? And does TauZY = viscosity * (dv/dz + dw/dy) be the correct expression for shear stress on the fluid?

Any insight much appreciated
