THD measurement

Hello there.

I'm trying to calculate the THD of the current on the AC Voltage Source (net 5) of the circuit below, but the result is kind of strange and I don't know what I'm doing wrong.

 

This is the circuit I'm working on.This is the circuit I'm working on.

 

As you can see, the THD is too damn highAs you can see, the THD is too damn high

The THD was to be near 120% or something. Please, may someone help me?

Hey Saldanha.

How are you?

 

Have you seen the example on Total Harmonic Distortion Calculation under Multisim Custom Simulation Analyses And Instruments Documents? 

It explains a bit about THD Calculation on Multisim and it has the code for this kind of measurement.

 

What do you think? 

Does it help?

Hi. Yes, I've read it, but I am using version 14.0 and the THD Analyser is for versions 11 and 12. I have tried the distortion analyser built in version 14.0 but did not have the result I was expecting either. 

Thanks for the help.
