Analyzing Kelvin Probe Designs with COMSOL Multiphysics®

October 4, 2017

Kelvin probes, a type of MEMS technology, provide a nondestructive and contact-free way to measure the work function differences of various material combinations.

Evaluating the Effect of Shell Thickness on Muffler Performance

October 3, 2017

Guest blogger Linus Fagerberg from Lightness by Design follows up a previous post with a discussion of one design consideration for the radiated sound in a muffler design: shell thickness.

Improving IFE Target Fabrication with a Droplet Microfluidics Method

September 29, 2017

A common joke is that fusion energy is 30 years away, and always will be. Researchers are using simulation to tackle the challenges involved with of inertial fusion energy target production.

Computing Porosity and Permeability in Porous Media with a Submodel

September 27, 2017

Porous materials have complex geometries and may therefore be difficult to model. Setting up a microscale submodel is a useful approach to find the porosity and permeability of the medium.

Analyze the Electrodynamics of a Magnetic Power Switch via Simulation

September 21, 2017

The AC/DC Module can be used to simulate electrodynamic devices, such as magnetic power switch circuit breakers. Follow along with this discussion to study the working principles of the device.

Modeling Irregular Shapes: How to Import Curve Data and Loft a Solid

September 20, 2017

Say you want to model an irregular shape, like a human head. How do you set up the geometry? Here, we go over how to do just that by importing curve data and lofting a solid.

Silicon Photonics: Designing and Prototyping Silicon Waveguides

September 19, 2017

John Tyndall tried to control the most visible form of energy, light, using 2 buckets and some water. Today, there is a more advanced device for this purpose: a silicon waveguide.

Studying the Thermal Performance of Phase Change Materials

September 18, 2017

Certain building materials, like plaster, are enhanced with phase change materials (PCMs) to assist in keeping buildings cool in the summer and warm in the winter. But how effective are they?
