Hi,

In my numerical model, I am working with piezoelectric devices multiphysics module. From electrostatics, I get surface plot which gives me electric potential developed in the model. However, I am interested in plotting AC voltage w.r.t time. I tried adding electrical circuits to my model and connected external I-terminal 1 to the terminal from electrostatics. And then I plotted a 1D global graph of voltage at node 1. However, the voltage plotted by this method and the one shown by surface graph from electrostatics varies significantly. Could someone please explain me the right way of plotting the voltage? 

Thanks,

Sajiree
