Modeling Laser-Material Interactions with the Beer-Lambert Law
Did you know that you can use the Beer–Lambert law to model laser–material interactions in COMSOL Multiphysics®? Learn how here.
Improving Your Meshing with Partitioning
It can be tedious to subdivide your CAD geometry into a finite element mesh. In this blog post, we demonstrate how to use a manual meshing method called geometric partitioning to do so.
Curve Fitting of Experimental Data with COMSOL Multiphysics
Have you ever had to work with experimental data in a model? Learn how to fit smooth curves and surfaces to experimental data using the core functionality of COMSOL Multiphysics®.
Ports and Lumped Ports for Wave Electromagnetics Problems
The Lumped Port boundary condition can be used to model boundaries through which a propagating electromagnetic wave will pass without reflection. Learn how to use this feature in your EM models.
Implementing a Thermostat with the Events Interface
Hot or cold? You can use the Events interface in COMSOL Multiphysics® to implement a basic on-off thermostat in your model for controlling a heat load. Get a demonstration of how to do so here.
Modeling a Periodic Heat Load
Interested in modeling periodic, or pulsed, heat loads? Modeling such a situation accurately and efficiently in COMSOL Multiphysics® is simple with the Events interface. Learn more…
Using Perfectly Matched Layers and Scattering Boundary Conditions for Wave Electromagnetics Problems
Learn how to use scattering boundary conditions and perfectly matched layers to truncate domains for your wave electromagnetics problem — and which technique is best for your modeling scenario.
Using General Extrusion Operators to Model Rotation
You can use the General Extrusion operators in COMSOL Multiphysics® to simulate rotating objects exposed to loads. A common real-world example of this is rotisserie-style foods.
