Hello,

I would like to perform a steady-state dynamics, Modal analysis with abaqus but the option is not available in the dialog box under Linear perturbation.
Do you know how I can activate it?

Thanks in advance :)

Do you have an existing frequency analysis? This is a prerequisite for SSD, modal.

Do you mean a step Linear Perturbation -> Frequency defined before?
