Unexplained behaviour of velocity vectors in Non -newtonian fluid flow

      Dear all, 

       I am trying to simulate the mixing patterns of a pseudoplastic fluid in a mixing tank. I have given property of the primary phase to follow a pseudoplastic behaviour. The contour velocities and the magnitudes look fine with the converged simulation. But the velocity vector plot looks unusually long as seen in this figure. Can someone please help out what is the mistake? 

      PS: The white layer seen in the middle is actually the plane on which I am trying to plot the vectors. I have also attached contour plot for clarity (with and without the impeller)

      Also please let me know if i should provide any details

      Hi Vidya,

      Try turning off Auto Scale first and seeif this works. Otherwise try turning on Fixed Length feature in Vector options.
