Modeling Acoustical Properties of Porous Media in COMSOL®
A guest blogger from the University of Shefﬁeld introduces the Johnson–Champoux–Allard–Lafarge (JCAL) model for analyzing acoustical properties of porous media.
How to Analyze Turbomolecular Pumps with COMSOL Multiphysics®
Modeling gas flow in a turbomolecular pump calls for specialized numerical methods, because at such low pressures, the gas molecules rarely collide with each other.
Modeling Parts Without Constraints in Your Structural Analyses
When building a solid mechanics model, there may be parts with prescribed loads but no constraints that can be reasonably applied. Learn different approaches and considerations for this scenario.
Fractals, Noise, and State Variables
Ever notice how the leaves of a fern seem to show a self-repeating pattern? Fractals are objects that exhibit some form of self-similarity at different scales. Learn how to model them here.
Using Layout Templates for Simulation App Design
Layout templates enable you to streamline your app design workflow in the Application Builder, while still leaving room to implement your own functionality.
The North Pole Models Product Distribution Challenges for the Holidays
Today, a guest blogger from the North Pole discusses using simulation to find out if his boss will be able to fit down all of the chimneys this holiday season.
