 March 2, 2013, 14:25 Boundary conditions problem for flow blockage analysis in a channel #1 New Member   Qasim Ali Join Date: Mar 2013 Location: Islamabad, Pakistan Posts: 18 Rep Power: 6 Hello friends, I am working for my MS thesis on a flow blockage analysis. I have taken the axissymmetric around y axis (x=0) on axis with velocity along y axis 24 m/s and x axis is zero. but when i enter in boundary conditions in fluent it shows x and y velocity of 2d case only but radial and axis velocity for axissymetric conditions and offcorase solution is not being initialized. Help me out. thank you
