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 |
Re: Asymmetry induced by the mesh
The mesh may have something to do with it, but it is also possible for the physics to result in an asymmetric solution if the symmetric solution is unstable. For instance, a round jet in a pipe will be drawn to one side, even though the geometry and boundary conditions are symmetric. It's the fluid dynamic equivalent of standing a pin on it's head.
