Thanks for the response.

If I set both to 16 in the Harmonic balance properties dialogue box it works. Both sets of tabulated data in the data display are as expected and  the same.

Same if I set both to 15.

But the problem is still there if I set both to 14.

The workaround for now seems to be to set both to 15 (or greater).

What I’m aiming at is to set up an optimisation using the HB simulation. Having access to the OP1dB() function on the schematic page would be ideal.

The formatting didn’t work out too well in my first attempt. Here is a copy of the text:

I’ve created and attached a simple, harmonic balance simulation which has equations y1 and y2 using the diode voltage on the schematic.
When I tabulate the values of y1 and y2 on the data display they are wrong.
u_RF is out of step with the y1 values. This looks like a bug to me.

Thanks for the suggestion zhu.

I checked and there were no blank lines in the sch file.

My problem was that I had the data plots in the schematic file and there was too much data to display.

I moved the data plots to a data display (dpl) file and the schematic would open. QucsStudio  then crashed when I tried to open the dpl file. It was ok if I deleted the dataset.

Finally I simplified the data display to reduce the number of plots that I had. Now I can run my 5000 iteration Monte Carlo analysis and display the data without QucsStudio crashing.
