How do I correctly simulate a three-phase circuit?

Hello everybody.

This is a circuit where a clockwise rotating
field (LED 1 lights up) or the left rotating field (LED 2 lights up) of a
three-phase motor / connection can be displayed. I am new to electronics and I found that simple circuit that I do not
understand, so I would like to simulate this circuit to understand the function
of the capacitors and diodes.

I've already looked for tutorials on google and youtube, but I can't find an explicit solution to my problem. Then I started to read the The EasyEDA Simulation eBook article, so I had my first positive experiences and results with the **waveform tab. **

My current problem is that I don´t know exactly how and where I correctly define the measuring probe and ground for showing me at wich time, how much Volt and Ampere is present at the LEDs.

Here you can find a link to the original circuit that I wanted to recreate: https://upload.wikimedia.org/wikipedia/commons/archive/5/57/20160922134435!Schaltung_Drehfeldmessgeraet.svg

Thanks for your help.

Please make your Project public and then post the url to  the simulation schematic back here.

See Sharing in the Tutorial.

Put an Ammeter in series with each LED.

This may help you to understand where to put your voltage and differential voltage probes:

Please move your 120k resistors away from the V2 phase wire, as in your example circuit.
