Geometry is the basic building block of any simulation, and while you can create models natively in OnScale, you may also decide to use an external geometry source. CAD tools provide focused and streamlined workflows for creating complex geometry and if you've already designed a model in another tool it can be quicker to use this geometry instead of recreating it in OnScale.
Let us provide you with a very simple definition first to get things clear. Certain materials tend to accumulate electric charges when a mechanical stress is applied to it. The piezoelectric effect is an effect that simply describes the fact that a pressure applied to a piezoelectric material will generate a voltage.
In this article we discuss how to pole piezoelectric materials in OnScale and walk through an example of how to rotate the material properties of Lithium Tantalate for the Y-cut angle in an LT-SAW.
In 1880 brothers Pierre Curie and Jacques Curie were working as laboratory assistants at the Faculty of Sciences of Paris. They discovered that applying pressure to crystals such as quartz, tourmaline and Rochelle salt generates electrical charges on the surface of these materials. This conversion of mechanical energy into electrical energy is called the direct piezoelectric effect. “Piezo” is derived from the Greek for “to press”.
In Part 1 of this Blog Tutorial we provided a more theoretical example of piezoelectric equations and the important coefficients to know.
Obtaining the correct piezoelectric material properties from a manufacturer datasheet and transforming those properties into the correct format for simulation can be a hassle.
In this article we discuss Genetic Algorithm (GA) optimization for a Solid Mounted Resonator (SMR) design using OnScale Command Line Interface (CLI) and MATLAB Optimization Toolbox.
In this blog post we discuss piezoelectric transducers and the best way to model them with finite element analysis (FEA).
In this blog post we discuss how ultrasonic sensors work and how a vibrating piezoelectric disc generates ultrasonic waves. We have also included an interactive demo to show you how to simulate an ultrasonic sensor in OnScale using Finite Element Analysis. An ultrasonic sensor is a system that can emit and receive ultrasonic waves. It is generally used to sense the distance to and from an object. It also belongs to the family of “transducers” because it generates ultrasonic waves from an alternating voltage. Thus, it transforms electrical energy into acoustic energy.
We are so thankful to our awesome customers! This post is a special “thank you” to all of you who attend our webinars and ask such excellent questions. It is through your questions that we learn what’s important to OnScale users and this, in turn, allows us to continuously improve our software. The conversations that start in our webinar Q&A often carry over into the OnScale offices and we’re always happy when we hear them coming up in our development meetings.
