Symmetric Meshing Error

Please login with a confirmed email address before reporting spam

Hi all,

I have a yz-axis symmetrical 3D model and I want to copy the mesh from one side to the other. In other words, I want to mirror the Mesh.

I've tried what Henrik Sönnerlind suggested in this Thread:
www.comsol.com/community/forums/general/thread/73291
but this only works if I have just ONE domain.
My model consists of several domains mirrored at the yz-axis. I fail to copy the mesh of several domains at once. I always got the error message "Different number of edge elements".
I tried it with two different Mesh operations, with "Copy Domain" and "Copy", but both gave the same error as stated above.
For clarity I attached the model with the error message.

Does anybody have experience with symmetric meshing?

Thanks in advance
Christian

Hi

it works for me (ok in te 5.2 beta but I'm sure its also valid for the previous versions.
What you had missed is that your default Free Tetrahedral was meshing all "Remaining" domains. Then the copy does not work because the destination is already meshed :)

Good luck

Hey Ivar

Thank you very much. You really solved the problem!
From the error message I got, I didn't expect it to be the problem of meshing "too much". I'd thought of a wrong number of faces from the geometry or similar...

Best regards
Christian
