Implementing a Thermostat with the Events Interface
Hot or cold? You can use the Events interface in COMSOL Multiphysics® to implement a basic on-off thermostat in your model for controlling a heat load. Get a demonstration of how to do so here.
Evaluating the Instability of a Space Arc Frame
Picture the Louvre Pyramid in France: This is a real-world example of a space arc frame. Simulation can be used to evaluate instability in this type of structure.
Using Degeneracy Breaking to Design a MEMS Biosensor
Researchers from Newcastle University in the U.K. used simulation to investigate the effects of material and geometric symmetry breaking in a degenerate mode sensor. Get the full story >>
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.
