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 […]

## 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 […]

## How to simulate a Piezoelectric Micromachined Ultrasound Transducer (PMUT) device in OnScale

A piezoelectric micromachined ultrasound transducer, also called PMUT, is an electronic device capable to generate ultrasonic sound waves. They have various applications: For example, they can be used to measure a distance into a medical device for example. The principle is quite simple A small circular area build in piezzoelectric material vibrate very quickly under […]

## How to simulate the propagation of a 2D ultrasonic wave in a steel plate with OnScale

If you want to understand the physics of sound wave propagation, I have another article more detailed on it here How to simulate the propagation of a 2D ultrasonic wave in a steel plate with OnScale: How to create a simple geometry model in Onscale How to assign time-varying pressure loads and boundary conditions How […]

## What is a sound wave & How does it propagate?

For this new article on the blog, I decided to go into a new domain of engineering I never talked about until now: Acoustics and Sound Wave Propagation! It’s always exciting to enter and discover a new type of physics because I start to see more possibilities around me and it allows me to understand […]
