On grid independence
 
Hi, I am modelling a 2D pulsatile flow in a conical tube with a velocity pulse at the inlet that last 40% of the cycle. For some time I have been trying to obtain a grid independent solution. I have run cases with 200 000 cells and one with 800 000 cells. From that I have 2 questions:

1) Is comparing the time-dependent velocity at one point a good way to judge of the grid independence? I ask this because I am getting quite different results form one case to the other.
