Engineering the Flow of Light Using Photonic Crystals
Did you know that the discovery of photonic crystals in 1980 came about because of an attempt to reduce the losses in semiconductor lasers in a specific frequency range?
Recursion and Recursively Defined Geometry Objects
Broadband antennas and metamaterials are 2 fields of engineering in which recursively defined geometry objects are a useful modeling capability. Writing methods makes this task easier.
How to Automatically Remove Small Details in Your Model Geometry
Have you ever wished for an automatic way to remove small details in your model geometry that are causing an unnecessarily fine mesh or a poor mesh quality? Enter the Remove Details operation.
Best Practices for Meshing Domains with Different Size Settings
Tip 1: Choose the order of your meshing sequence operations. Tip 2: Use a single operation to mesh multiple domains. Keep reading to learn how to ensure the high-quality meshing of model domains.
How to Automate Meshing in Frequency Bands for Acoustic Simulations
There is a large frequency range involved in acoustics phenomena, which means that modeling acoustics problems requires meshing a large wavelength range. COMSOL® offers an efficient way to do so.
Analyzing Vibrations in Rotating Machinery Due to Bearing Misalignment
You can use structural analysis to compare the angular velocity, axial displacement, and bearing reaction moment on the shaft for rotating machinery with aligned and misaligned bearings.
Automatic Time Step and Order Selection in Time-Dependent Problems
Here’s an intro to the time-dependent solver log in COMSOL Multiphysics® and an in-depth look at the theory behind discrete time-stepping schemes and optimal time steps and discretization orders.
Using Simulation Software in the Courtroom
Simulation is inherently a representation of reality. In court, lawyers establish what did or did not happen in reality and why. So what happens when simulation software is used in a legal case?
