Modeling Microresonators with Electrostatic Actuation
Learn how to model electrostatically actuated MEMS resonators and get an intro to terms such as equilibrium point, pull-in, pull-in voltage, and time harmonic response of a biased resonator.
Optimizing the Power of a Piezoelectric Energy Harvester
When it comes to a piezoelectric energy harvester, the design configuration should maximize the level of power transfer. How can simulation be used to improve the design of an energy harvester?
A Thermoviscous Analysis of Acoustic Radiation Forces
Learn how to determine acoustic radiation forces, including thermoviscous and acoustophoretic effects, in the COMSOL® software.
Improving Nuclear Reactor Designs with Simulation
Take a look inside the dynamics of a nuclear reactor — and then see how you can use multiphysics simulation to improve their design.
Finding a Structure’s Best Design with Topology Optimization
Think about the first architects who designed a bridge above water. The design process likely included several trials and subsequent failures before they could safely allow people to cross the river. COMSOL Multiphysics and the Optimization Module would have helped make this process much simpler, if they had computers at the time, of course. Before we start to discuss building and optimizing bridges, let’s first identify the best design for a simple beam with the help of topology optimization.
Nestlé Sweetens the Candy Production Process with Simulation
Question: How does a well-known candy company ensure that each of their signature chocolate bars has the same consistency, texture, and taste? Answer: Fluid flow simulation!
What Is Geometric Nonlinearity?
If you perform structural mechanics analyses, then you have most likely encountered the concept of geometric nonlinearity. But what exactly does geometric nonlinearity mean?
How to Improve Your Paddle Stroke with Simulation
To take a closer look at a paddle stroke, for activities like canoeing and dragon boat racing, we set up a 2D model in COMSOL Multiphysics® and visualize the flow pattern around the paddle blade.
