Eigenvectors & RBE2

Eigenvectors & RBE2

Eigenvectors & RBE2

(OP)
HI,

I have some problems in Normal Modes analysis. There are a lot of RBE2 elements in my model and i don't understand why there are no informations (eigenvectors values) at each dependents nodes. Moreover, the dependents nodes components are presents in the mass matrix MGG.

Dependents nodes are in g-set !

Can you help me ?

Regards

RE: Eigenvectors & RBE2

Hello!,
I don't understand well the question relating eigenvectors & RBE2 rigid links elements, if you perform the modal analysis (SOL103) using the nastran solver you will be able to see in the screen of your preprocessor both the eigenvalues & mode shapes, please explain what you are looking for exaclty, upload your model, or a picture, etc...

Best regards,
Blas.
