Hello everyone,
I have a question regarding modal analysis in Code_Aster. My results seem correct for DX, DY, and DZ. However, when I look at the rotational modes (DRX, DRY, DRZ), I observe some discontinuities between the nodes at the beam boundaries and the rest of the structure. I can see some kind of jump appearing where it should not.
Has anyone ever encountered this problem?
I’ve attached the .comm file, the .med file, and an image to illustrate what I’m referring to.
Best regards,
