Frequency response of 3D model of laterally vibrating resonator (LVR) similar to design from 2013 MTT paper by Gong and Piazza. A conventional frequency sweep (red circles) does not resolve spurs or the main resonance compared to the FastPZE simulation (black line). Both simulations took the same amount of simulation time. Achieving similar resolution with the conventional algorithm would have required 28X more computation time.
