How to Choose Between Boundary Conditions for Coil Modeling
3 approaches for truncating a domain when modeling an EM coil in free space: the Magnetic Insulation and Perfect Magnetic Conductor boundary conditions as well as the infinite element domain.
Model How the Bubbles in a Glass of Stout Beer Sink, Not Rise
Ever notice how the bubbles in certain kinds of stout beer sink to the bottom of the glass instead of rising to the top? We explain this phenomenon using fluid flow simulation.
Accessing External Material Models for Magnetic Simulations
Get a demonstration of how access external material models for EM simulations with a hysteresis example. Plus, get an overview of the available functionality for modeling ferromagnetic materials.
Studying Transient Heat Transfer in a Fin Design with an App
A guest blogger and author presents a simulation app that he designed to study transient heat transfer in a nonprismatic fin.
Control Current and Voltage Sources with the AC/DC Module
Did you know that you can use the Terminal boundary condition to dynamically switch between excitation types during a transient simulation? This is useful for modeling power supply, for example.
Multiphysics Simulation Provides Accurate Muffler Designs
A guest blogger from Lightness by Design, a COMSOL Certified Consultant, shares how multiphysics simulation provides accurate results when designing automotive mufflers.
Keeping Track of Element Order in Multiphysics Models
Whenever you are building a finite element model in COMSOL Multiphysics®, it is important that you are aware of the element order that is being used. We demonstrate how to do so here.
Guidelines for Modeling Rotating Machines in 3D
Learn how to use the Rotating Machinery, Magnetic interface in COMSOL Multiphysics® to model a 3D generator, and then compare our results with an analogous 2D model. Part 2 of 2.
