I've built a circuit which models a capacitive measurement system my lab is designing. When I run a time-domain analysis to find the maximum current through an inductor (labelled L1 in the linked circuit), said current is dependent on the size of the timestep - smaller timesteps cause larger currents. I did the analysis by hand and find a value smaller than any of the values given by the simulator. Any ideas?

Further information: timestep needs to be on the order of 10^-6s. Change in the max current from a timestep of 10^-6 to 10^-7 was on the order of 10.
