Structural Mechanics Tutorials: Rigid Connector and Linear Buckling

Andrew Griesmer June 6, 2013

Continuing our structural mechanics tutorial blog series, we have created two more videos of different functionality existing in COMSOL’s Structural Mechanics Module. The first post in the series introduced you to the Structural Mechanics Module via a linear elastic analysis of a bracket, and the following post included two supplemental videos for adding Initial Strain and Thermal Stress to the this model. Next up we have two more “mini-tutorials” — this time outlining the Rigid Connector feature and the Linear […]

Double Pendulum Simulation Tutorial

Pawan Soami May 22, 2013

Dynamic simulation of a double pendulum system can easily be performed using the Multibody Dynamics Module available in COMSOL Multiphysics. This module enables the mechanical simulations of assemblies of flexible and rigid bodies, often coupled with other phenomena such as from heat, electrical, and others.

Digging into COMSOL’s Geomechanics Module

Andrew Griesmer April 19, 2013

I will always remember a Geotechnical Engineering class I took during the pursuit of my Civil Engineering degree. It contained both the high and low points for that academic semester; the lab portion was a lot of fun, learning about (read: playing with) the different soils and clays existing in the state of Georgia. The final project, on the other hand, tasked us with designing a retaining wall to match certain specifications — a tough and lengthy assignment. A retaining […]

Calling All Audiophiles: Loudspeaker Analysis Video

Bethany Nine April 12, 2013

When given the choice, we’d all prefer our loudspeakers to project perfect sound; having a phone conversation with someone who sounds like a robot caught in a windstorm is less than ideal. The quality of the sound is, naturally, dependent on how well the speaker is designed, and COMSOL Multiphysics is the perfect tool to simulate and optimize loudspeaker designs because of its easy-to-use multiphysics nature. For a loudspeaker analysis to be accurate, you must be able to simulate from […]

Structural Mechanics Tutorials: Adding Initial Strain and Thermal Stress

Andrew Griesmer April 4, 2013

Back in January, I presented a video tutorial introducing the Structural Mechanics Module here on the blog. The video described the steps necessary to perform a static linear analysis on a bracket geometry. Now, to help you better understand the extra functionalities that exist within COMSOL Multiphysics and the Structural Mechanics Module, we are also creating additional tutorial videos of this bracket. The first two “mini-tutorials” to accompany the static linear analysis video focus on adding initial strain and thermal […]

What Is COMSOL Multiphysics?

Andrew Griesmer March 6, 2013

You may be wondering “What is COMSOL Multiphysics?” In short, COMSOL Multiphysics is a comprehensive simulation software environment for a wide array of applications, but structured and user-friendly for all to use. The best way to answer the question of what our software can do is to show you. This is why we have created a video that gives you a brief overview of the capabilities you can possess with the software in your hands.

Boosting COMSOL’s Cooperation with Siemens PLM Software

Phil Kinnane February 19, 2013

In April last year, we entered into a partnership with Siemens PLM Software and started developing the functionality that would connect COMSOL Multiphysics® simulations to Solid Edge® CAD modeling. Siemens gave us access to their tool, and we were quick in developing LiveLink™ for Solid Edge® as part of the version 4.3a release. This project led to boosting our cooperation with Simens PLM Software, as we had already implemented Parasolid® to be an integral part of the CAD Import Module […]

Inductive Heating of a Billet Simulation Tutorial

Andrew Griesmer February 18, 2013

Induction occurs when a metal object moves in the presence of a magnetic field inducing a current in that object. The induced current causes it to heat up (called inductive heating), as all current does. Yet, simulating these two coupled physics together can be difficult to do as they are intrinsically based on different time scales. COMSOL Multiphysics is able to cleverly simulate them through combining the frequency domain modeling of the magnetic field with a stationary simulation of the […]

In Silico: Numerical Simulations in Biomedical Engineering

Fanny Littmarck January 30, 2013

Students at Ohio State University can take a course on numerical simulations in biomedical engineering with Richard T. Hart. In the course, they will learn how to use computer modeling to solve biomedical engineering problems. Hart is now providing anyone who is interested in this application area with three video tutorials from the course via the Ohio State University iTunes U page.

Joule Heating Simulations Tutorial

Fanny Littmarck January 29, 2013

One of the classic multiphysics couplings in engineering and science is Joule heating, also called resistive heating or ohmic heating. Some Joule heating examples include heating of conductors in electronics, fuses, electric heaters, and power lines. When a structure is heated by electric currents, the device can reach high temperatures and either structurally degenerate or even melt. The design challenge is to remove this heat as effectively as possible. COMSOL eases these challenges by providing a specialized multiphysics interface for […]

Video Tutorial: Introduction to the Structural Mechanics Module

Andrew Griesmer January 24, 2013

The Structural Mechanics Module has numerous capabilities, enough for a video containing all of them to last days. This video demonstrates one of the many mechanical capabilities of COMSOL Multiphysics, by outlining a Static Linear Analysis. The chosen physics interface for this problem is Solid Mechanics, one of 13 physics interfaces in the Structural Mechanics Module. The video shows step-by-step how to set up the model of a bracket with a standard workflow (i.e. import the geometry, create global parameters […]
