I am trying to plot the resistance(x-axis) vs voltage(y-axis) 1D relation by fixing the vibration frequency at 72Hz ,but it gave me error: "Failed to evaluate variable "

I have added 2 physics : AC/DC circuit and piezo-electric device

I have set up "Parametric sweep" of resistor from 1e5 to 1e6 ( 10 steps)

I have added frequency domain study by fixing the vibration frequency at 72Hz and select fully coupled

I am not sure if I set up studies correctly , should I add "stationary study" after "frequency domain" study?
or should I use "frequency domain model" study?

I am confused
