Best Practices for Meshing Domains with Different Size Settings

July 9, 2019

Tip 1: Choose the order of your meshing sequence operations. Tip 2: Use a single operation to mesh multiple domains. Keep reading to learn how to ensure the high-quality meshing of model domains.

How to Automate Meshing in Frequency Bands for Acoustic Simulations

June 26, 2019

There is a large frequency range involved in acoustics phenomena, which means that modeling acoustics problems requires meshing a large wavelength range. COMSOL® offers an efficient way to do so.
