How to Calculate a Capacitance Matrix in COMSOL Multiphysics®

June 7, 2017

Calculating the capacitance between two conductors is simple, but adding more conductors to the mix (as is the case with touchscreens, transmission lines, and capacitive sensors) adds complexity.

Analyzing the Structural Integrity of an Induction Motor with Simulation

May 11, 2017

The AC induction motor was invented by either Nikola Tesla or Galileo Ferraris, depending on who you ask. Either way, you can evaluate the structural integrity of this device with simulation.

Capturing Eddy Current Losses in a Permanent Magnet Motor Design

May 4, 2017

Permanent magnet (PM) motors are becoming more prevalent in transportation due to their energy efficiency. You can study Eddy current losses in a PM motor design with the AC/DC Module.

How to Postprocess Fields over Arbitrary Geometries

April 4, 2017

Check out this useful modeling trick: You can query the results of your model within an arbitrary geometric subregion by implementing an integration during postprocessing.

Analyzing Hearing Aid Receivers with Lumped-Parameter Modeling

March 17, 2017

Modeling complete hearing aid systems is extremely computationally expensive. Enter lumped-parameter modeling, which enables you to couple a system component to a test setup for validation.

Simulating the Electrothermal Transients in Superconducting Magnets

March 9, 2017

In order to design superconducting magnets for a particle accelerator, such as the Large Hadron Collider at CERN, researchers need to simulate and optimize their electrothermal transients.
