AC voltage generator or siulation error?

https://www.circuitlab.com/circuit/526c93ru8x7k/rectifier-w-smoothing-capacitor/

I tried to simulate a simple AC rectifier circuit . The output is not what is expected. Already there is no AC voltage at the voltage generator . May I chose a bad element or is there something wrong with the simulation?

thanks in advance

Try floating the V2, D3,D4 line and grounding one side of R1. Add node names and use them.

Hi, I'm a newbie to all this but this works: In the Simulate/Time Domain - change: Stop Time to (1/60)*25 and Time Step to (1/60)/30. Now run the Time Domain Simulation. I don't know why this works, maybe someone else can explain it?

I forgot to mention that these "times" are explained in the CircuitLab Textbook in Chapter 2, Schematics & Simulations Tutorial under the Time-Domain Simulation section. However, because I'm new to all this, it's still a bit gobbledygook to me at present.

If I only apply a simple voltage generator it cannot measure any voltage on its output
