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
2 interfaces for manually defining the deformation of finite element mesh: Deformed Geometry and Moving Mesh. Learn when and how to use each in this blog post…
