Course: Defining Multiphysics Models
There are 3 approaches to setting up a multiphysics model in the COMSOL® software: Fully automatic, manual with predefined couplings, and manual with user-defined couplings. Here, we discuss #1.
How to Perform a STOP Analysis with COMSOL Multiphysics®
Interested in structural-thermal-optical performance (STOP) analysis? We go over the theory, background, and how to perform such an analysis in the Ray Optics Module.
Understanding Classical Gray Body Radiation Theory
Imagine how efficient an incandescent lamp with an infrared suppressing black body filament would be. Alas, classical gray body radiation theory tell us this “dream lamp” is an impossibility…
Simulating the Tunneling Current Across a Graded Heterojunction
Interested in semiconductor design? Get an intro to the theory behind quantum tunneling as well as a demonstration of simulating the tunneling current across a graded heterojunction.
3 Approaches to Modeling Moving Loads and Constraints in COMSOL®
Learn 3 ways to model moving loads and constraints in COMSOL Multiphysics®: using variables, interpolation functions, and paths imported from CAD geometries.
Self-Consistent Schrödinger-Poisson Results for a Nanowire Benchmark
This benchmark model of a GaAs nanowire validates the Schrödinger-Poisson Equation multiphysics interface, which is useful for modeling systems with quantum-confined charge carriers.
Nonstandard Constraints and the Power of Weak Contributions
For a flexible and physics-independent way to extend the applicability of the COMSOL Multiphysics® software, you can implement nonstandard constraints using the so-called weak contributions.
How to Use Numeric Ports in Your RF Analyses
When performing RF analyses in the COMSOL® software, you can use numeric ports to compute the mode of a port with an arbitrary shape. This demonstration includes a waveguide adapter example.
