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 …
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 …
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.
This simple 2D model of a steel block with a void region shows how simple the setup process can be using the new PZFlex Designer Mode. The full workflow from model import to post processing outputs is demonstrated in the short video.
GDSII is an industry standard file format for integrated circuit (IC) layout artwork which is now compatible with PZFlex. The video offers a quick demonstration of how the tool works and how to generate a model from a GDSII file.
The Designer Mode interface has been designed to allow mechanical wave propagation and piezoelectric models to be set up very easily. The 2D Transducer Model shows how to set up both loading types within the GUI.
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.
Quick demonstration of the new PZFlex Analyst and Post Processor interface.
The 2-Port SAW example demonstrates the speed and ease of using the Designer Mode interface to set up and run a simulation with CAD geometry.
