Sun Guest Posts: n/a	Friends, I am simulating a 3d flow in a circular pipe, which is inclined at an angle of 15 degrees below the x-axis. When I see the cartesian x-velocity vectors, after having got the converged solution, I notice the vectors are in one direction (in positive x direction). But when I look at the axial velocity vectors (in cylidrical system) I see vectors both in positive and neagitve x directions. Is this correct ? If it is correct is it because of the secodary flows ? Let me know. A beginer
