Modeling Free Surfaces in COMSOL Multiphysics® with Moving Mesh
You can model free liquid surfaces that do not undergo topology changes using moving mesh functionality in the COMSOL® software. Here’s a thorough guide on how to do so.
What Is the Doppler Effect?
A siren passes by and you hear a change in pitch. A bug swims across a puddle, causing ripples on the surface. A star in the sky has a reddish hue. These are all examples of the Doppler effect.
How to Model Conductors in Time-Varying Magnetic Fields
You can use the AC/DC Module to perform frequency-domain simulations for conductors in time-varying magnetic fields by describing the skin effect.
Happy Birthday, Inge Lehmann
Inge Lehmann was a Danish geophysicist and seismologist who used seismic waves generated by earthquakes to answer the age-old question: What’s really at the center of the earth?
How to Search for a Specific COMSOL Multiphysics® Application
The Application Libraries in the COMSOL® software contain a variety of examples that demonstrate specific features and modeling techniques. Learn how to quickly search for a specific one.
Analyzing Operating Mode Options for Helical Antennas
Simple but effective, helical antennas are used in smart implants, RFID, radio, GPS, space probes, and more. You can use RF simulation to analyze the operating mode options for these antennas.
Happy Birthday, Claude Shannon
Claude Shannon ushered in a new age of communications technology, contributing ideas about testing digital circuits, coding messages in binary, and programming artificial intelligence.
Modeling Fluid-Structure Interaction in a Heart Valve
The average human heart beats 100,000 times per day, but what if the person has cardiac issues? Modeling fluid-structure interaction in a heart valve can help researchers develop new treatments.
