Default Asymmetry induced by the mesh

Dear all,

I have symmetric domain and symmetric boundary conditions, but I get asymmetric solutions. I am simulating the whole 360 physical domain.

Can the asymmetry be due to the mesh? Is there any evidence of this? Can anyone briefly explain this to me, or give me the references to books or papers dealing with this subject?

Thank you very much,

Ale

switch in unsteady solver, and check if your solution is steady or not. If you take von karman example with high-Re (symmetric model + symmetric BC), you'll get typical unsteady solution which isn't symmetric
