Optimizing FBAR Design with FEA using PZFlex – Recording

Gerry Harvey Webinars 0 Comments

Question and Answers Q: Why does the 1D model take >10s? One would assume that the computational effort is comparable to a typical Mason model (transmission line based), which runs in milliseconds. A: An analytical method like Mason’s or KLM is always going to be quicker than FEA for the simple problems which they are designed. That said, much of …

Five Tips for Better Optimization

Gerry Harvey Blog 0 Comments

Optimization is a powerful tool, allowing engineers to discover better designs quickly and efficiently. Here, we look at 5 tips to ensure that your optimization studies yield the best possible results in a short timeframe. Tip #1: Simplify the simulation as much as possible In order to explore a large number of designs it’s important that the simulations are as …

Pentagonal FBAR Simulation

Kevin Chan Videos 0 Comments

First few cycles of a pentagonal shaped FBAR. The video shows surface velocity, like you’d see on a laser vibrometer in the lab. Full simulation runs for 3,000 cycles and builds up a full spectral analysis of the device from a single run! This design was Optimized using Matlab’s Genetic Algorithm via FlexConnect.

PZFlex simulation of a plane wave propagating from the left side of a steel block, encountering an angled defect at approximately 1/3 of the way along its length. This simple example showcases a number of fundamental features of ultrasonic wave propagation, such as reflection, refraction and mode conversion. Note the Rayleigh wave running along the crack surface.
