Computing and Using Partial Inductance with COMSOL®
COMSOL Multiphysics® version 6.0 brings new functionality for computing total and partial inductances and AC resistances. Get an overview here.
Creating Schlieren-Type Visualizations in COMSOL Multiphysics®
Did you know that Schlieren imaging might predate written history? Here, we explore this ancient imaging technique with CFD modeling.
Introduction to Computing Radiative Heat Exchange
Follow along as we continue our discussion on the foundations of radiative heat transfer modeling. (Part 3 of 3)
Modeling Incident Radiation in Radiative Heat Transfer
Get an introduction to modeling incident radiation on a surface with the Surface-to-Surface Radiation interface in the Heat Transfer Module. (Part 2 of 3)
Modeling Emissivity in Radiative Heat Transfer
In Part 1 of a blog series on modeling radiative heat transfer, we discuss the concept of surface emissivity.
How to Compute the Projected Area of a CAD File in COMSOL®
Learn about three approaches to computing the projected area of a CAD file and when to use each one.
How Long Does It Take an Engineer to Turn on a Light Bulb?
Misconception about electricity: Electrons carry the energy in an electrical circuit. Today, we investigate this theory with simulation.
Wrapping and Warping Geometries for Analysis in COMSOL®
CAD parts are typically designed in an undeformed, as-manufactured state. When it comes to analysis, however, we are only interested in the deformed, as-assembled state.
