Fully Coupled Hydromechanical Modeling of Fractured Media
Dr. Qinghua Lei of ETH Zürich demonstrates a novel method for modeling fully coupled hydromechanical processes in fractured media with 2 examples: fluid injection and underground excavation.
Simulating Wind Load on a Sports Car’s Side Door and Mirror
Vroom vroom: In this blog post, we use large eddy simulation (LES) and structural analysis to analyze wind loads and airflow on the door and side mirror of a sports car driving at high speeds.
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.
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.
Modeling Sound Transmission Loss Through a Concrete Wall
The sound loss transmission (STL) through a building component is the logarithmic ratio between the total incident power on the structure relative to the total transmitted power.
