Hi!

AC:
Making ac simulation of simple source-R-C-gnd serial circuit on eSim i always get flat curve at 0v.
Ngspice return, plot of Vsource(?!) and Vc, wich are both zero ...
Why is v source zero?
I tried with ac, sine and other sources, always the same.

DC:
If i add resistor R2 in paralel with C, then i get correct values for input Vs and output V_R2,  for the case of sweep of value of R2.
With that resistor in paralel with C, for ac analisis Vc and Vs are again zero.

TRANSIENT:
Second nag is that making transient simulation i get already from ngspice one dimensiolal graf, values have extension only in y directon.
For all specified cases I have no error mesages from ngspice.

Thanks
