Symmetry Cone

      Hello everyone, 


      I am trying to impose symmetry over a cone structure I have. I know that normally to impose axial symmetry; a 2D section should be cut and rotated around the axis, that is a little hard for the model I am trying to simulate (I attach a screenshot) 


      how can I implement symmetry here? if I can 


      Thank you so much for your help,

      The axis is defined as y=0 (in Fluent).  However if you want an annular domain (or cone etc) the axis doesn't need to be within the meshed zone. Ie for an annulus the axis is y=0 but the domain could be at    0.5 < y < 2.0

      but even with the changing of the y axis, can i implement cyclic symmetry ?

      Yes, but the axis of the domain MUST be y=0  (in Fluent).  If it's 3d it doesn't matter.
