## Create Heterogeneous Materials from Images

In this month’s tips and tricks video, we are going to demonstrate how you can create heterogeneous materials using images. Click below to watch as I walk you through the process. To help you follow along, we have included the video transcription below.   There’s no reason to learn software programs through trial and error, […]

## AltaSim’s Multiphysics Simulation Role in Knee Replacements

Medical devices continue to improve the health and lives of millions of people worldwide, and simulation plays a critical role in developing them. Simulations enable engineers to assess the performance of their medical devices for a wide range of conditions with greater patient safety and less expense than in vivo or in vitro testing. In a free upcoming webinar, Electromagnetic

## Benefits of the Finite Element Method

Computational simulation is a powerful tool for solving complex engineering problems that involve the finite element method (FEM). FEM is a numerical technique that divides a domain into smaller elements and approximates the governing equations at each element. By using computational simulation, engineers can perform FEM analysis faster, more accurately, and more efficiently than using

## 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

## Using COMSOL Multiphysics to Deconstruct a Complex Problem into a Simpler Version

I love a good challenge, and as the newest member of AltaSim’s team, I am fortunate to have excellent mentors here who constantly challenge me to expand my knowledge. I have been teaching myself how to use COMSOL, and one of my most recent challenges from the team was to solve a turbulent flow problem,

## Exploring Sound Absorption Through Acoustic Metamaterials

The fast-growing area of acoustic metamaterials, specifically those composed of subwavelength periodic artificial structures with specific designs, has drawn significant research attention. In this article, we compare acoustic metamaterials to the limitations of conventional acoustic materials in sound absorption, and what we discover is acoustic metamaterials are far more effective for low-frequency applications. LIMITATIONS OF

## Incompressible Potential Flow with COMSOL Version 6.2

COMSOL continues to make updates to Version 6.2, and in this month’s tips and tricks video, we are going to demonstrate how you can use the new update for Incompressible Potential Flow, which can be used to replace Laplace’s Equation to initialize fluid flow equations. Click below to watch as I walk you through the

## Solver Improvement for Modeling of Chaotic Systems

COMSOL has made some solver improvements to Version 6.2 of repeatability in chaotic simulations, which has been helpful for a particular project we’re working on for a customer. In this month’s tips and tricks video, we share an example of how this solver improvement helps us get the same answer with the same initial input

## Useful Postprocessing Techniques Using the Graph Marker Tool

In this month’s Tips and Tricks video, I am going to demonstrate some useful postprocessing techniques using the “Marker” and “Graph Marker” subnodes. A very simple problem of acoustic scattering is used as an example, however, demonstrated postprocessing techniques can be used for any other physics. Click below to watch as I walk you through

## Adapting the Electrical Grid for Green Energy Webinar

Earlier this month, AltaSim hosted a webinar in conjunction with COMSOL that focused on Adapting the Electrical Grid for Green Energy. Our host, Josh Thomas, a senior engineer at AltaSim Technologies, shared how the renewable energy industry has matured substantially over the past two decades. Currently, the renewable energy industry provides more than 20% of
