Superposition of several harmonic signals

Hello everyone,

I am using Joule Heating with periodic boundary conditions (electric current pulses). I want to get the temperature-time plot for a specific Point in my structure. For that I thought Comsol would solve it faster if those 1m+ pulses were to be generated with superposition of harmonic signals (Fourier stuff).

I tried to use Frequency-Transient study but I couldn't figure out how I can define several frequencies and related amplitudes.

Could you please help me on that?

A tutorial dealing with this Topic would also be very helpful.

Thanks,
Bartu
