In this article, I will describe how to understand and visualize correctly the results coming out of a PMUT ultrasonic sensor simulation in the OnScale Post-processing Mode. What is a PMUT? Piezoelectric Micromachined Ultrasonic Transducer (PMUT) are MEMS-based piezoelectric ultrasonic transducers. Unlike bulk piezoelectric transducers which are typically thickness mode resonators, PMUTs are based on […]
All the things you always wanted to know about electronic filters
I started some weeks ago to talk about FEA simulation in the acoustic area with this article… and I am just starting! Today, I wanted to present to you a “new” type of electronic device that you can simulate in FEA: Filters! (Ok, nothing new about filters… they have been here for decades! But being […]
How to calculate Natural frequencies and mode shapes of a PZT Disc in OnScale?
If you become familiar with OnScale, one of the things that you may wondering is how to calculate natural frequencies of your model… This is the kind of things that deserves to be explained a bit more in details! The real world is time domain. You might be used to doing modal analysis, but it’s […]
The 10 most useful commands you need to know about in Onscale Analyst Mode
In this article, I will tackle the 10 most basic commands to know about in Onscale Analyst mode But first… What is Onscale Analyst Mode? Here’s a short video which shows you the 3 modes you can use to perform an analysis: There are 3 modes available in Onscale: The Designer mode allows to create […]
Why would you ever put your FEA in the cloud? and how?
A lot of companies now are talking about the « cloud » but not everyone knows what it actually means… As you might be required at some time or another to run your FEA “into the cloud”… better understand what is means ;-) As usual, let’s break down what it means and make everything simple to understand […]
How to measure voltage in OnScale Double Tonpilz Acoustic Simulation
A lot of people ask me about how to extract the voltage in OnScale, so I decided to make a quick video to show how to do that. So here’s the basic problem: Let’s suppose that you want to model two Tonpilz Transducers (or BLTs) in 3D in OnScale. You apply voltage to one of […]
