Vinyl Records: A Sound All Their Own

September 5, 2014

Since their arrival on the music scene in the 1930s, vinyl records became a staple in the recording industry. While their use decreased due to digital recording methods becoming more dominant over the last couple of decades, this older medium continues to be valued for its unique and rich sound. Let’s take a closer look at this method of analog recording.

2D Axisymmetric Model of a Conical Horn Antenna

September 4, 2014

We’ve blogged about how you can save time setting up your electromagnetic models by using symmetry, anti-symmetry, and periodic boundary conditions. Today, we’ll show you a model that takes advantage of axisymmetry — a conical horn antenna model.

A Strategy for Designing Corrosion-Resistant Materials

September 3, 2014

Billions of dollars are spent each year in the U.S. to repair corrosion damage. To help reduce the high cost of corrosion, engineers at the Naval Research Laboratory (NRL) in Washington, D.C. are using multiphysics simulation to gain a better understanding of the fundamental mechanism. A successful research outcome at NRL will establish the correlation between metal microstructure, corrosion, and mechanical strength. Material designers could then develop stronger, corrosion-resistant materials using this new information.

Using Effective Mass for Thermomechanical Calibration

September 2, 2014

Micromechanical sensors are crucial to many standard commercial products in nanoelectronics and nanomechanics. These are sensors that are so small they operate on the nanoscale, with parts measuring in billionths of a meter. Researchers at the University of Alberta are exploring ways to find the effective mass — the mass of a particle when reacting to a force — of micromechanical sensors in a faster way. This measurement is key to performing thermomechanical calibration.

Surface, Volume, and Line Plots: Visualizing Results on a Heat Sink

September 1, 2014

Plotting visual simulation results on a model geometry is a great way to unveil the sometimes-mysterious physics happening behind the scenes in a device. Like learning a language, knowing how to use postprocessing tools helps designers investigate and understand their designs and processes more fully. Surface, volume, and line plots are three of the most common plot types used in postprocessing, and are applicable to many simulations.

Designing Future Technologies with Gallium

August 29, 2014

Gallium is an element with a strong presence in the commercial market, particularly the electronics industry. Recent research has brought the spotlight back on this unique metal and its use in new technologies. Here, we take a closer look at this element and what the future holds for it.

Thermal Contact Resistance Simulation

August 28, 2014

How does thermal contact resistance affect heat transfer? As the sizes of electronic devices continue to decrease, effective heat management becomes even more important. Today, electronic packaging has transitioned from its original purpose of providing mechanical protection and interconnection to also serving as a means of heat dissipation to the outside environment. Using a model from the Model Gallery, we explore the role of thermal contact resistance on heat management in a simple electronic package and heat sink assembly.

Magnetic Cooling Technology in Refrigeration

August 27, 2014

While the concept has been around for quite some time, magnetic cooling technology has only recently emerged as a potential method of refrigeration within households. Here, we take a closer look at how this new technology offers a greener approach to preserving foods.
