I made a simple circuit looking at the Vf of a diode, After I disconnect bottom wire from diode & add low ohm resistor to gnd for test, I delete resistor & reconnect bottom wire on diode & now I have no current.

I have tried replace diode, restart app, etc... but it is stuck with.
If I short to gnd I get 0V & full current as expect.

I have not tried yet... Make new circuit from scratch, try this circuit in another version (eq win32)

I am using SimulIDE_0.4.15-SR1_Win64 on win7p

Someone please to test my .simu file in case its just me.

Hi Tonigau.

You are right, there is a problem here.
It's weird, the problem only happens if you use both Ampmeter and Voltmeter.
Using only one at a time it works as expected.

I will have a look.

It also conducts when the Zener volt is set other than 0.
I add a resistor to VoltMeter input & works too.

Yes, the problem only happens when Ampmeter & VoltMeter are connected directly to the diode.
This is already solved in development version.
