end Model1;
I ran teh simulation.  Plot the current  n in capacitor 1, but then tried to alsoplot the current in capacitorr 2, the system crashed!!! 

Please, help me on this.

Hi Jose,
One way to solve the problem is to add the to capacitors together into one.
Also your second capacitor is very big, 45F, is that intended?

Hope that helps!
