Modeling Linear Motors or Generators in COMSOL Multiphysics
We demonstrate how to customize a linear periodic boundary condition to model linear motors and generators in COMSOL Multiphysics®, with an example of a tubular generator used for wave energy.

Part 2: Mapping Variables with General Extrusion Operators
Learn how to use the General Extrusion operators, which are designed to handle nonlinear mappings and the mapping of variables between geometric entities of different dimensions. Part 2 of 2.

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.

Accessing Nonlocal Variables with Linear Extrusion Operators
In some modeling scenarios, you may need to transfer variables from one region of a computational domain (the source) to another (the destination). This can be done with an extrusion operator.

Göttingen, a University Town with a Rich Scientific History
Göttingen, Germany, has a rich scientific history and is also home to a prestigious university — the University of Göttingen — and a COMSOL office! Learn more about this impressive city…

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.
