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.
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.
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.
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.
7 Ways to Use the Application Builder and COMSOL Server™
Create apps for colleagues and customers, enhance your model, and set aside a simulation project for later use: Get details on these and 4 other ways you can use the Application Builder.
Multistudy Structural Optimization of a Bracket
Weight reduction is a key focus in the automotive industry, where lightweight materials equal more fuel-efficient cars. Here, we perform a multistudy structural optimization of 1 component.
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.
Deformed Mesh Interfaces: Rotations and Linear Translations
Using the finite element method often involves modeling solid objects that are rotating and translating within other domains. See how to use the deformed mesh interfaces to model these movements.
Model Translational Motion with the Deformed Mesh Interfaces
