I have a closed series circuit consisting of a capacitor, inductor resistor and diode. There is no external voltage source.

Typical capacitor size is 0.02 mfd.  Inductor is 370 mhy, resistor is 9 ohms
Typical initial conditions (time zero) are capacitor volts = 20, inductor current = 120 ma.

Beginning clockwise around the loop, current flows clockwise out of the  inductor into the positive side of the capaciotr
Current is flowing in the forward direction of the diode (of course).
Need simulation to track voltage at any node after time zero
