Modeling the Dynamics of a Gyroscope
Gyroscopes and spinning tops aren’t just old-fashioned toys. Using models of these 2 structures, we illustrate the remarkable properties of rotating bodies.
Simulate Three-Phase Flow with a New Phase Field Interface
The Three-Phase Flow, Phase Field interface, used for modeling separated three-phase flow, computes the shape of the interfaces between the 3 phases and accounts for interactions with walls.
Use Editor Tools to Simplify Your App-Building Process
Get a demonstration of how to create an app using a simple simulation example, as well as how to perform common user interface creation tasks more easily in the Application Builder.
New Impedance Boundary Conditions for Acoustics Simulations
Get a comprehensive overview of the Impedance boundary conditions and how to use them for your acoustics simulations in COMSOL Multiphysics®.
Accessing External Material Models for Structural Mechanics
In COMSOL Multiphysics®, you can access not only material models derived from external libraries but also material functions programmed by yourself. We demonstrate with concrete damage model.
Does the Current Flow Backwards Inside a Battery?
What happens inside a battery? Does the current flow from negative to positive electric potential? Here, we explain the potential profile inside a battery during discharge and recharge.
Different Ways to Count Particles in COMSOL Multiphysics
There are 3 ways you can count particles in your particle tracing simulations in COMSOL Multiphysics: during postprocessing, using accumulators, or with the Particle Counter feature.
Exploiting Periodicity in Models with High Péclet Numbers
In the study of chemical species transport, a high Péclet number means the ratio of advection to diffusion is very high. Learn how to exploit periodicity when modeling this type of problem.
