Hello All, I have run a full flow for a centrifugal pump and got the results. The pressure contours are so good as shown below. However, the velocity contours show zero velocity all over the pump. When I used Slice on ParaView, I found that the velocity has values on the impeller surface as I go through the depth which means that it's not zero all over the pump. What's interesting is that the pressure values are correct. I can't figure out why this is happening. My concern is that I am following a tutorial and the velocity contours are normal in his example. Any guess why this might be happening?
