Terminal Velocity, Drag Coefficients, and FIFA World Cup™ Predictions
Is it possible to predict the winners of the FIFA World Cup™? We forgo consulting a psychic and instead analyze the terminal velocity and drag coefficients of different balls with CFD simulation.
Modeling Free Surfaces in COMSOL Multiphysics® with Moving Mesh
You can model free liquid surfaces that do not undergo topology changes using moving mesh functionality in the COMSOL® software. Here’s a thorough guide on how to do so.
How to Model Conductors in Time-Varying Magnetic Fields
You can use the AC/DC Module to perform frequency-domain simulations for conductors in time-varying magnetic fields by describing the skin effect.
Two Methods for Modeling Free Surfaces in COMSOL Multiphysics®
We take you through 2 methods for modeling free surfaces in the COMSOL® software: the level set and phase field methods. Learn how to use each method and their benefits.
How to Solve a Classic CFD Benchmark: The Lid-Driven Cavity Problem
We demonstrate how to solve a classic benchmark problem in the field of computational fluid dynamics, the lid-driven cavity problem, using the COMSOL® software.
