raunakjung is on a distinguished road
I am doing a parametric study. My simulation is transient and I am using FFt to find the dominant frequency.

I have used the FFT but for some cases While carrying out FFT I get the following error :

FFT:: processSignal - Data set size is less than 2 points.

I am confused about the fact why FFT works for some cases while not for others.

please help me to solve the following

Thank You
