Hi Verpies, the only problem with the simulation is the series resistor as I was looking at 0.3 ohms due to wiring only, the dampening resistor would be in parallel and switched in on the second half of a cycle.
You can double-click on that resistor and change its value.
Also you can right click on the black background and add another component (e.g. a 2nd resistor).
Pressing the space bar will allow you to move existing components.

Remember, that in reality the parallel LC tank will also have some resistance in series with the inductor ...unless your inductor is superconducting.  The same can be said about the ESR of the capacitor...

Thanks for the information Verpies, that puts that circuit to bed for me. I have another idea that I will try out on the simulation software before posting it for comments.

Can anyone tell me why falstad or LTspice don't simulate the current cycle going into the negative half for an inductor with an ac sine wave source voltage?
