Hello!!I am a new user of ABAQUS. I have a question about obtaining of the frequency response function in ABAQUS. In the first step I calculate the natural frequency using the step linear perturbation(procedure type)/frequency.I think that obtaining the frecuency response function, I need to use in the second step the steady-state dinamic,modal.I don`t get to plot the amplitude of modal-frequency graphs.I would apreciate much if someone could help me about this question.
