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?
Introduction to Modeling Acoustic-Structure Interactions in COMSOL®
To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.
Frequency Response of Mechanical Systems
Read this blog post for a detailed look at damped mechanical systems, a guide to setting up frequency-response analyses in COMSOL®, and a discussion of how to interpret your results.
