How to Compute the Acoustic Radiation Force
Did you know that objects can actually be moved by sound? This effect is called acoustic radiation, and it is an acoustophoretic phenomenon that can be analyzed in the COMSOL® software.
Cloaking Advancements for Flexural Waves in Elastic Plates
A European research group discovered a theoretical framework to both overcome the limitations of cloaking and achieve exact cloaking for flexural waves in Kirchhoff–Love plates. Get details >>
Improving the Power of Optical Systems via Component Design
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
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
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
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
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
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.
