## Finite Element Analysis and the Benefits of Computational Simulation

Finite element analysis (FEA) is a method of solving complex engineering problems involving structures, fluids, heat transfer, and other physical phenomena. FEA divides the problem domain into smaller and simpler parts called finite elements, and then applies mathematical equations to describe the behavior of each element and the interactions among them. FEA can find approximate […]

## How Not to Miss the Boat with Multiphysics Simulation

Multiphysics simulation is a complex, powerful computational technique that lets you explore all the real-world physical interactions that a complex product may encounter during use including fluid dynamics, electromagnetism, acoustics, and optics. When you’re designing and testing a product with a low to no error margin, Multiphysics simulation is extremely accurate. Take for example the

## It’s a Small World – Designing Piezoelectric Acoustic Transducers as Devices Miniaturize, Part 1

The increasing miniaturization and sophistication of electronic products–ranging from consumer media devices, to medical diagnostic tools, to defense-related sonar applications–presents a bounty of utility and ease for consumers, and an ongoing challenge for design engineers. These seemingly disparate products (audio/mobile device speakers, certain non-invasive medical devices and sonar arrays) share in common a reliance on

## It’s a Small World – Designing Piezoelectric Acoustic Transducers as Devices Miniaturize, Part 2

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

## Modeling and Simulation: Opportunity

Modeling and Simulation: Opportunity   “It’s not just what you do it’s also why you do it” – Part 2 With all these advantages of modeling and simulation that were documented in Part 1 of this blog where is computational analysis and virtual prototyping being used and what is the opportunity for future use? A

## Modeling and Simulation: Motive

Modeling and Simulation: Motive   “It’s not just what you do it’s also why you do it” – Part 1   As scientists and engineers involved with modeling and simulation it is natural for us to focus on the intricacies of the tools that we use and to instinctively value the use of computational analysis.

## Seal Well Solves Green House Gas Problem

Seal Well Solves Green House Gas Problem in Oil and Gas Wells   It is not very often that AltaSim gets to openly brag (with permission) about one of its clients, but this is one of those times. We are excited to share about the work of Homer L. Spencer, P. Eng, Seal Well Inc.

## MRI Webinar

MRI Webinar (Recording Accessible Until December 18, 2015)   On June 18th, our very own Kyle Koppenhoefer joined Walter Frei, PhD, Applications Engineer, COMSOL, to present a free Webinar on Simulating MRI Heating of Medical Implants. As we wrote about last week, Magnetic Resonance Imaging (MRI) is one of the most widely used and safest

## MRI – Magnetic Resonance Imaging and Simulation

MRI – Magnetic Resonance Imaging and Simulation Magnetic Resonance Imaging (MRI) is one of the most widely used and safest imaging modalities for medical diagnostics. Despite this, one of the major technological challenges facing the biomedical imaging world has been the issues created when a patient with metallic medical implants suffers the need (for any

## Computational Model for Bolometer Design

Computational Model for Bolometer Design   Bolometers are used in a number of applications including night vision cameras, astronomy, and particle physics to measure the power of incident electromagnetic radiation. The principle of operation is shown in Figure 1: when a strip of conducting material is exposed to incident electromagnetic radiation, energy is absorbed and
