It seems quite clear to me that adding a 1N4001 model to LTSpice IV must be some twisted rite of passage! I must be missing something simple.

Got the Diodes in, thanks!

Trying to get the fancy wave forms to show what I expect for circuit operation is a challenge right now.

 

Graph shows.... Just needed to be patient for the 200ms mark.... How do I speed this up/adjust the scale to the 9V, it appears as max 60mv. Maybe the input dc v is not set...

I got the 9V scale to show and the input wave form and the blue line corresponds (not sure anymore). Is there a way to speed this up?

It takes about 48 seconds to finish running on my computer; but I have a Pentium core 2 running at 2.13GHz. If you don't have a dual core processor, it'll take longer. If you are running on a system that doesn't have a co-processor, it will take a very long time.

You could speed it up by reducing the number of cycles on V2, and reducing the frequency. Try 200Hz and 600 for Ncycles, or just 200 and 200.

 

Good thing wookie stepped in. It turned into a Spice problem, which I couldn't tell anybody how to do.

Gee...it seemed so simple in the beginning!

 

You might find LTSpice helpful. You can do all kinds of interesting things with it once you get the hang of it.

 

I installed LTSpice IV on a jumpdrive (at work). I am sure it will perform better at home on an I5 hp laptop.

 

It'll run quite slowly on a flash drive. You can just copy the LTC folder into a temporary folder on the desktop, and run it from there by double-clicking scad3.exe in the LTspice4 directory.
