Model Magnetic Materials in the Frequency Domain with an App
Easily convert B-H or H-B curves into effective B-H or H-B curves using the Effective Nonlinear Magnetic Curves Calculator simulation app.
Modeling Linear Motors or Generators in COMSOL Multiphysics
We demonstrate how to customize a linear periodic boundary condition to model linear motors and generators in COMSOL Multiphysics®, with an example of a tubular generator used for wave energy.
Creating Ultrafast Polymerase Chain Reaction Tests with LEDs
Researchers at the University of California, Berkeley, used simulation to develop an LED-based polymerase chain reaction system that shows potential for point-of-care testing. Get the full story.
Analyzing Mutual Inductance in Different Coil Arrangements
Mutual inductance measures the amount of change required for a current flowing through one circuit to create a current in a nearby circuit. Simulation can be used to compute mutual inductance.
Should We Model Graphene as a 2D Sheet or Thin 3D Volume?
Graphene is a 2D sheet of carbon atoms that is 1 atomic layer thick. However, is graphene actually 2D or is it just incredibly thin, like a very fine piece of paper? How should it be modeled?
