How to implement "steady state dynamic analysis" in abaqus

Hi all,

Here is what I'm interested to model in Abaqus:

I have a shell model, clampled on the booundaries. I want to excite it in a frequency range of 10 to 100 Hz with 10Hz intervals and I want to report the complex displacement of a particular node set at each frequency.

I read in Abaqus documentation of "Direct-solution steady-state dynamic analysis" that:

"Steady-state dynamic analysis provides the steady-state amplitude and
phase of the response of a system due to harmonic excitation at a given
frequency. Usually such analysis is done as a frequency sweep by
applying the loading at a series of different frequencies and recording
the response".

I define STEP as:

*step, name=step1, perturbation

*steady state Dynamics, direct, frequency scale=LINEAR

10, 100, 10, 1

My problem is how to define the load? Should I define a harmonic load for each frequency (with Amplitude and w) and repead it for each frequency?

Should I define just magnitude and it will consider the excitation at the frequencies that I already defined in STEP?

Should I define a tabular ampitude with just frequency number and amplitude ( and it will automatically consider it az harmonic excitation for each frequency)?

I really appreciate any input.

Thanks,
