3 Approaches to Modeling Moving Loads and Constraints in COMSOL®

October 22, 2018

Learn 3 ways to model moving loads and constraints in COMSOL Multiphysics®: using variables, interpolation functions, and paths imported from CAD geometries.

How to Model Conductors in Time-Varying Magnetic Fields

May 25, 2018

You can use the AC/DC Module to perform frequency-domain simulations for conductors in time-varying magnetic fields by describing the skin effect.

Common Pitfalls in Electrothermal Analysis

April 17, 2018

In the real world, electromagnetic heating often involves a nonlinear temperature. Learn some common pitfalls that occur during this type of electrothermal analysis and how to overcome them.

Should I Fillet the Geometry in My Electromagnetic Heating Analysis?

November 30, 2017

You want to analyze electromagnetic heating around sharp corners in your simulation. Do you round off the corners by adding a fillet? We go over cases where you should and shouldn’t do so.

Which Turbulence Model Should I Choose for My CFD Application?

July 6, 2017

Modeling turbulence in the COMSOL® software? Find out which turbulence model you should use, depending on your CFD modeling scenario.

How to Use Model Methods to Accelerate Your COMSOL® Workflow

June 22, 2017

Methods aren’t just for enhancing simulation applications built in the Application Builder. In fact, you can create methods to streamline and automate repetitive modeling operations.

How to Model the Optical Properties of Rough Surfaces

June 6, 2017

We develop a computational model for calculating the optical properties of rough surfaces, such as incident light on a dielectric material with random variations in height and thickness.

How to Create a Randomized Geometry Using Model Methods

June 5, 2017

What does cheese have to do with setting up a COMSOL Multiphysics® model? Here, we use the random holes in a piece of Swiss cheese to demonstrate creating randomized geometries with methods.
