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.
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.
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.
Keynote Video: Rapid Prototyping for Sonar Systems
Engineers at Northrop Grumman follow a 4-part rapid prototyping design phase: Design, manufacturing a prototype, testing and design verification, and manufacturing of the final design.
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.
