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

Fluent allows you to be axisymmetric only along the X axis.

Exactly.

The simple solution is to rotate your model.
Keep in mind that the whole model has to be above the x-axis.
