SO the circuit below is an approximation to an electrostatic energy harvesting system and device. Basically I want to observe the charging voltage waveform across the cap C3. In real life the cap charges in a few hours but I do not think LTspice likes completing that many iterations without converging on a steady state condition. It just either stops working after a while or gives a 'singular matrix' error (after the first iteration)depending upon the value I use for the cap C3.
Is there anyone that is handy with Ltspice that could tell me how to make it like this sort of transient analysis?
Perhaps this system just has too high source impedance for LTspice?
