Hello, I'm a mechanical student.
I'm doing a cyclic symmetry analysis using NX NASTRAN. When I compare the eigenvector between the fan sector and the complete structure, I get an error. My model is not convergent.
But I'm working on hexahedral elements and when I increase or decrease my interpolation polynomial, the value of the frequency doesn't vary.
Could you give me some advice on this issue?
Yours sincerely , Rodolph21
