Dear Sir/Madam
I want to use Sine voltage as a source in an RLC circuit. I want to study the driving point impedance with frequency sweep. But when I use sine voltage, I get an error like The DAE is structurally inconsistent.
The simulation works fine with DC and AC voltage, and in both cases, the plots are exactly same.
How to resolve this problem.
Dear Manoj Samal ,
This is an expected behavior of the solver. When apply sinewave or any other waveform means that you would like to make dynamic analysis which contains a transient solution and a steady sate solution.
The AC analysis is steady sate analysis of harmonic input in frequency domain
In this case one is interested in three parameters, the amplitude, the frequency and the phase while the waveform is assumed to be sinusoidal.
In AC case one works with impedance concept. In sinewave input one works with differential equations.
Best wishes

Sinuswave is in most CAD Programs takled as not a time domain wave. It has an amplitude and possibly phase and frequency as parameters. Ciruit analysis is made based ov phasor presentation of sinus wave. In time-domain analysis other that sine waves can be chosen (triangel, puls-series, etc.)
