Building a Magnetohydrodynamic Multiphysics Model in COMSOL®

June 19, 2019

Magnetohydrodynamic models call for fluid dynamics and electromagnetics couplings. To do so, you can set up bidirectional couplings between all physics equations or building a simplified model.

Using Discontinuous Meshes for Conjugate Heat Transfer Modeling

November 21, 2018

You can use different discontinuous meshes in neighboring domains in COMSOL Multiphysics®. This capability comes in handy, particularly when modeling conjugate heat transfer problems.

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
