Simulating the Motion of a Self-Stable Bicycle
Did you know that modern bicycles are designed to be self stable? They’re good at keeping balance while moving uncontrolled. You can simulate this effect in COMSOL Multiphysics®.
Designing New Structures with Shape Optimization
Get a comprehensive background on using shape optimization to design new structures, with the example of a classical beam thickness problem.
Changing the Dimensions of a Model Using Shape Optimization
If your model has a single objective function to be improved, a set of geometric parameters to be changed, and a set of constraints, you can find the optimal structure without any remeshing.
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.
How to Solve for the Brachistochrone Curve Between Points
See how to use built-in mathematical expressions, the Optimization Module, and COMSOL Multiphysics® to solve for the brachistochrone curve.
