How Spreadsheets Are Used in Engineering

September 19, 2012

We’ve noticed that a lot of our customers use spreadsheets, such as Excel®, as part of the modeling process. They use them for storing material property and other data, such as from experiments or other information about workflow associated with their engineering project, and then import this data into COMSOL Multiphysics®. Spreadsheets are also the forum for taking in results from COMSOL software and using this to compare, optimize and verify these material properties. Let’s delve deeper into how spreadsheets […]

Solar Radiation: How Engineers Can Stay Cool on the Beach (Maybe)

August 29, 2012

The end of August marks the end of summer here in New England. Already nostalgic and unwilling to let the season go, I decided to look into some “beach physics”. In May we released a new solar radiation feature in our Heat Transfer Module that will be helpful in many solar applications — including how to avoid overheating on the beach, apparently. Here’s how engineers can stay cool on the beach.

Modeling a Light Bulb, All Forms of Heat Transfer

August 21, 2012

When it gets dark, you flick on the lights. If you were to model this simple example, you would need to take all forms of heat transfer within consideration; convection, conduction, and radiation are all at play when a light bulb is flicked on.

3D Printing: Hottest Topic in Manufacturing

July 27, 2012

Additive manufacturing, or 3D printing as it is more widely known as, is on everybody’s mind right now. Manufacturing folks, engineers, and even the general public have taken an interest in 3D printing. In other words, this is not just a fascinating phenomenon to those in the industry — additive manufacturing has been generally accepted as the next “cool” thing in manufacturing.

Space Fuel: Oak Ridge National Laboratory to Produce Plutonium-238

July 4, 2012

The end of July marks the beginning of a $20 million R&D project led by the Oak Ridge National Laboratory (ORNL) to produce and process plutonium-238. The U.S. space program will be using the Pu-238 that is to be produced by ORNL as fuel for future deep-space missions.

Follow-Up on Venus Transit of the Sun 2012

June 8, 2012

After reading about the COMSOL users over at MACCOR in David’s blog post I decided to watch Venus’ transit of the Sun live via their online stream from Tulsa, OK. This was a once in a lifetime opportunity that I, like many people around the world, did not want to miss.

News in Particle Tracing for 4.3

June 1, 2012

There are many exciting new features in the Particle Tracing Module for COMSOL Multiphysics version 4.3. The secondary particle emission feature is particularly fascinating. “This new option for the Wall Condition allows you to model filter multipliers and multipactors, which were previously very difficult to model”, says Dan Smith, Development Team Leader at COMSOL. A mathematical expression, like a logical expression containing the particle energy for instance, can be used to determine the number of secondary particles to be released. […]

Heat Transfer: Accounting for the Radiation of the Sun

May 22, 2012

Knowing the sun’s radiation and thermal effects is very important to designers within the building industry, especially in designing “green” buildings. Heat transfer also plays a vital role in designing outdoor devices in terms of maintaining temperatures in extreme hot or cold environments. To use the words of Nicolas Huc, project leader for the Heat Transfer Module development at COMSOL in France: “it makes a huge difference if you forget to take the sun’s radiation into account.”
