I want to make an addition to my last post. I said that after making the change it will simulate, but I am not sure it is simulating correctly as I don't have that much experience with the PWL source (I have never had occasion to use it).
I thought I would just make that clarification.

Here's something to try other than my first suggestion. It seems to at least simulate now with the option Repeat turned on. What I did was set the first time to 1e-008 instead of zero in the PWL Source listing. Also, you are going to have to change the amp rating on the Coil as it is blowing out each time the simulation starts. I have mine set to 20A.
I hope this helps some.

Your welcome. I try my best. Nestor may have better information than I do. When he is available I hope he reads this post and may provide an explaination to both of us.

Edit: As far as the conductor blowing, I went back and set it to 1A and it worked fine. It is my theory that with the capacitor acting a short at power up there may be a current rush above the rating for a brief time, just enough to blow the coil at .5 A (this is just theory and I could be wrong). I am unable to measure this surge, so this is conjecture on my part.

Hi All,
This looks like a convergence problem. I was able to simulate this circuit by changing TMAX. Select Simulate>>Interactive simulation setting, I reduced TMAX from the default value of 1e-5 and changed it to 1e-7 sec.

Thanks Tien, that worked great on my machine. Your time and response is greatly appreciated.
