Keynote Video: Locating Leaks in Pipe Networks with a Simulation App
Sebastien Perrier of Echologics discusses a simulation application used to locate leaks in underground pipe networks in his keynote presentation at the COMSOL Conference 2016 Boston.
How to Model an Anechoic Coating
Modeling an anechoic coating involves finding the smallest unit cell, truncating the geometry, and analyzing the wave diffration. The COMSOL® software includes predefined interfaces to do so.
Using the Domain Decomposition Solver for Thermoviscous Acoustics
Learn how to use the Domain Decomposition solver, a memory-efficient iterative algorithm with inherent parallelism on the geometric level, in COMSOL Multiphysics®.
How to Use Acoustic Topology Optimization in Your Simulation Studies
Today, guest blogger René Christensen of GN Hearing discusses the importance of acoustic topology optimization and how to apply it in COMSOL Multiphysics. Topology optimization is a powerful tool that enables engineers to find optimal solutions to problems related to their applications. Here, we’ll take a closer look at topology optimization as it relates to acoustics and how we optimally distribute acoustic media to obtain a desired response. Several examples will further illustrate the potential of this optimization technique.
