If you are doing a parametric sweep of frequency, and have configured the solver properly, then it will presumably step through, compute, and store the solutions at all of the frequencies listed in your parametric frequency sweep. You should then be able to access those solutions via the pull-down menus that are accessible via the various results plotting options. Now, if you are instead talking about something else, such as having a single "excitation" frequency while expecting to see some other frequencies being generated by means of physics interactions occurring within your structures/materials, then you are talking about a non-linear physics problem. In that case, you should probably not be trying to study this in the frequency domain at all, but should consider a time-domain model.
If that advice doesn't help, then I suggest you post your model to the forum so that others can take a closer look at it and can then provide more helpful and specific comments and advice. Good luck.
