Finite Element Analysis and the Benefits of Computational Simulation

General, Multiphysics Modeling, Simulation, Thought Leadership /

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

COMSOL Multiphysics, Thought Leadership /

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

COMSOL Multiphysics, Thought Leadership /

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

Useful Postprocessing Techniques Using the Graph Marker Tool

COMSOL Multiphysics, Tips & Tricks /

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

COMSOL Multiphysics, Simulation, Thought Leadership /

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

Exporting High-Resolution Probe Data During a Parametric Sweep

COMSOL Multiphysics, Tips & Tricks /

Through experience, we discovered that if you want to develop an accumulated probe table, it doesn’t export the full resolution that you requested under “Updating probes.” So, in our latest Tips & Tricks video, I walk you through three steps you can take to export high-resolution probe data during a parametric sweep. Click below to

Reducing the Need for Physical Prototyping with Sensor Design Webinar

COMSOL Multiphysics, Simulation, Thought Leadership /

This past month, AltaSim hosted a webinar in conjunction with COMSOL and Tech Briefs, where they demonstrated how to reduce the need for physical prototyping with sensor design. Through a live demonstration of sensor simulation using Multiphysics software, they showed how Multiphysics simulation captures the physical behavior of sensors more accurately than single physics simulations. Our
