Hi

if you do power transmission at a fixed frequency, its much better to use the frequency domain solver in the "omega" mode. Then you gve the signal amplitudes and the responses are the amplitude (and phases if applicable, note that if an amplitude becomes complex, you will only get the real part displayed, so you must explicitely access real() and imag() parts separately for the postprocesing.

Time series is good for "transient" effects, and to see how long these take to die out, but are too long to solve for constant sinus type excitations

I do not understand how to represent the expression of voltage V = Vmax * sin (omega * t + fi), in the frequency domain. Would using the Fourier Transform?

Hi

Check the equations, its already in a harmonic development, you define the amplitudes (and phase if complex or in phasor expression) on the BC's the solver assumes the "sin()" and you define only the frequency in the solver tab. YOu can also define a series of frequencies, for a frequency span, as for any parametric sweep. But if you work at 50 Hz you define jsut freq=50[Hz].
Check the doc and the examples in the model library

Results values are amplitudes, so you need to use the sqrt(2) correction, or if more complex phase dependence, extract real and imag parts and combinethem accordingly
