I have a very elementary setup in the attached file where i'm trying to visualise the voltage output of a three phase source.
When I click the scope, I get two flat lines (one for the real component and one for the imaginary). I expected to see a time varying sinusoid.
However when I do the simulation in "Continuous" mode (by changing the parameter in the "powergui" block), the sinusoid appears perfectly in the scope.
Why doesn't it show properly in Phasor mode?
I'm not sure what i'm doing wrong

Phasors are complex numbers representing sinusoidal voltages and currents at a particular frequency. They can be expressed either in Cartesian coordinates (real and imaginary) or in polar coordinates (amplitude and phase). As the electrical states are ignored, the phasor solution method does not require a particular solver to solve the electrical part of your system. The simulation is therefore much faster to execute. Keep in mind, however, that this faster solution technique gives the solution only at one particular frequency.
