Acoustic Topology Optimization with Thermoviscous Losses

February 28, 2018

A guest blogger from GN Hearing discusses including thermoviscous losses in the topology optimization of microacoustic devices, such as hearing aids, mobile phones, and metamaterial geometries.

Analyzing the Viscous and Thermal Damping of a MEMS Micromirror

January 29, 2018

Micromirrors are efficient and inexpensive. Here, we go over 2 types of analyses for a MEMS micromirror design, frequency-domain and transient, using the COMSOL® software.

How to Use Dispersion Curves to Analyze Fluid-Filled Pipes

November 8, 2017

Modeling a fluid-filled pipe is both a time-consuming and computationally expensive process, but there’s a way to streamline the process: a guided wave propagation approach via dispersion curves.

Keynote Video: Using Simulation to Develop Reliable Audio Transducers
