 December 11, 2012, 07:04 Axis Symmetry BC #1 New Member   Manish Join Date: Oct 2011 Location: Jamshedpur Posts: 6 Rep Power: 7 Is it necessary that in FLUENT the axis symmetry boundary should be aligned with x-axis. Is it possible to apply 'axis' as boundary condition to axis aligned with y-axis. I am applying this axis symmetry condition for first time, so had doubts. kind regards..manish

Not true; if the axis is y or z you will get amg error; for axis symmetric problems the axis of symmetry MUST be x!!!

axis of symmetry must be X-axis as Daniele mentioned.

You cannot set the axis.
