Hi I want to draw the velocity contours in different sections along the bend of U-pipe may somebody guide me how I can do this? I was aware that I need to draw an iso-surfaces but the problem I have no idea how I can distribute the surfaces along the bend because the angle of bend vary in each section? any other idea will be appreciated?
