Particle Tracing in a Component of a Quadrupole Mass Spectrometer
Use multiphysics simulation to analyze the design of quadrupole mass filters (the key component of quadrupole mass spectrometers) and investigate the effect of fringe fields on these devices.
Evaluating an Insulin Micropump Design for Treating Diabetes
Researchers from the University of Ontario Institute of Technology used simulation to develop a MEMS-based micropump that could administer insulin injections in a safe and painless way.
Analyzing the Design of a Thermoelectric Device for Cryotherapy
Researchers at the University of Birmingham in the U.K. turned to simulation to investigate the potential of using a thermoelectric cooler, or Peltier device, to cool a cryogenic probe.
Do Bumblebees Use Their Hairs or Antennae for Electroreception?
A research team at the University of Bristol combined the power of physical experiments and simulation to study how exactly bumblebees use electroreception.
How to Analyze an Induction Motor: A TEAM Benchmark Model
In this blog post, we demonstrate the modeling of the three-phase induction motor described in Testing Electromagnetic Analysis Methods (TEAM) workshop problem 30a.
How to Dynamically Modify Geometries in Simulation Apps
We demonstrate how to use the Method Editor to create an app for: 1.) dynamically creating and modifying geometry parts and 2.) applying appropriate physical specifications and mesh.
Methods That Accelerate the Modeling of Bandpass-Filter Type Devices
Designing bandpass-filter type high-Q devices with the finite element method in the frequency domain? Here are some methods you can use to speed up the modeling process.
How to Model Solar Concentrators with the Ray Optics Module
