In Part 1, we provided a basic introduction to Piezoelectric materials. In this blog, we will take a look at specific products that present a challenge for design engineers due to the need for increased output within smaller devices. Mics and Speakers Piezoelectric materials are used extensively in acoustics. Microphones contain piezoelectric crystals that convert […]
Engineers post process their simulation results for reasons that range from better understanding their results to communicating those results to others. Developing labels that clearly identify the conditions for a simulation communicates the critical input parameters for the plotted results. In this Tip and Trick, the simulation engineers at AltaSim will show a way to

As discussed in Part 1, engineers are tasked with designing electrical components that can withstand the increased thermal and mechanical loads required of today’s ever-more-powerful electronics. Sometimes these are entirely new designs built from the ground up, and subjected to holistic testing and prototyping during the R&D phase. But often, manufacturers seek to merely tweak

The airbags in your car; the camera on your video doorbell; the phone or other electronic device you’re reading this on right now. The everyday products that make modern life possible wouldn’t be able to run without key electrical components that maintain functionality and stability for years at a time. And yet, these electrical components

An electromagnetic wave consists of a coupled oscillating electric field and magnetic field which are always perpendicular to each other. By convention, the “polarization” of electromagnetic waves refers to the direction of the electric field. In 3D geometry, arbitrary polarization is naturally defined by the prescribing the directions of all three components of the electric

Multiphysics Modeling of Cooled RF Ablation In previous blog posts, we have provided extensive discussion on the Use of Computational Simulation of Medical Technology[1]. To provide a specific demonstration, this blog post will focus on describing the implementation of a multiphysics simulation of a cooled RF ablation (C-RFA) device. Traditional vs Cooled RF technology Traditional

In working with our customers, AltaSim often seeks to solve an initial problem in two dimensions to save computational time. The CAD we receive from our customers is routinely in three dimensions, and our engineers need to reduce the dimensionality of the solution space. In the past, our engineers spent significant time re-creating CAD in
