Improving the Power of Optical Systems via Component Design

January 21, 2015

Adaptive optics are used to improve the power of optical systems — beyond the obstacles imposed by the optical medium. See examples and learn how to model adaptive optics systems.

Simulating Vibration and Noise in a Washing Machine

January 15, 2015

When designing a washing machine, you must account for a nonuniform distribution of clothing during operation. Simulation can be used to analyze vibration and noise in this household device.

Introducing Nonlinear Elastic Materials

January 9, 2015

Examples of nonlinear elastic material models: Ramberg-Osgood, Duncan-Chang, Hardin-Drnevich, Power law, and more. We discuss how to apply nonlinear elastic materials in your analyses.

Computing View Factors with the Heat Transfer Module

January 2, 2015

Interested in computing geometrical view factors in COMSOL®? There are operators for postprocessing that correspond to the operators used to generate surface-to-surface equations. Learn more.

Biomechanical Model Evaluates Human Response to Vibrations

December 31, 2014

Take a look at a biomechanical model of the human body in a sitting posture, which can be used to analyze how vibrations (like those from a moving vehicle) affect different parts of the body.

New Piezoelectric Modeling Interface in COMSOL 5.0

December 30, 2014

As of version 5.0 of COMSOL Multiphysics®, there is a new interface for simulating piezoelectric devices; it has predefined features that make it easy to set up and run a piezoelectric model.

How to Obtain Fatigue Model Parameters

December 26, 2014

2 challenges when modeling fatigue: 1.) selecting a suitable fatigue model for your application and 2.) obtaining the material data for the selected model.

Modeling a Surface Micromachined Accelerometer

December 23, 2014

There are plenty of MEMS manufacturing techniques, but surface micromachining is preferred because it can merge electronic components and freely moving mechanical parts onto one substrate.
