Learn about the capabilities of COMSOL Multiphysics® for modeling frequency-domain electric currents in this in-depth guide.
Using Different Physics Interfaces for RF Electromagnetic Heating Models
RF heating problems can be modeled with both the RF Module and the AC/DC Module. Learn more about their capabilities here.
Combining Volumetric Conductor Models and Lumped Elements
With the AC/DC Module, it is possible to connect a full-fidelity volumetric conductor model to a lumped circuit element model. Learn how here.
Modeling the Pulsed Laser Heating of Semitransparent Materials
Laser light is often used to rapidly heat materials within the semiconductor processing industry. Here, we explore this method with heat transfer simulation.
Intro to Modeling Transient Heating of Solids in COMSOL Multiphysics®
Transient heat transfer models are easy to set up and solve, but the interpretation of their results can lead to confusion. Here, we explore this scenario with a simple heat transfer model.
Computing Orbital Heat Loads with COMSOL Multiphysics®
As of version 6.1, the Heat Transfer Module includes a new interface for defining satellite orbit and orientation, orbital maneuvers, and varying planetary properties.
Losses in Three-Phase Transmission Lines
Explore how to model the losses in three copper wires in a linear and an equilateral arrangement.
How Large of a Model Can You Solve with COMSOL®?
Ever wonder how large of a model you can solve in COMSOL Multiphysics®? It depends on memory requirements, model size, and the dimension of your finite element problem.
