Hi
it depends what you want to do: if you want to analyse a transient situation you should use a time stepping and define your loads or other BC's with a time varying equation.
but if you have a steady state oscillation (harmonic response) use the frequency domain solvers which does a development in omega and omega square, you define the frequency or frequency span/range in the solver setting.
Check the equations to understand how the equations look like in time series and frequency sweep solver modes

Good luck
