Introduction to Modeling Acoustic-Structure Interactions in COMSOL®
To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.

Optimizing PID Controller Performance with COMSOL Multiphysics®
PID controllers involve three components that must work together simultaneously, and it can be challenging to get each of them just right. That’s where process control simulation comes in.

Frequency Response of Mechanical Systems
Read this blog post for a detailed look at damped mechanical systems, a guide to setting up frequency-response analyses in COMSOL®, and a discussion of how to interpret your results.

Efficient Parameter Control and Usage in COMSOL Multiphysics®
Any model can benefit from a proper parameter list. Learn how to control and use model parameters more efficiently with features such as parameter nodes and forms.

Keynote Video: Improving Process Understanding with Applications
When an organization’s research spans across many industries, consistent product quality becomes the name of the game. That’s why Huntsman Advanced Materials turned to simulation applications.

Analyzing Topology Optimization of a Photoacoustic Spectroscopy Cell
Signals generated via photoacoustic spectroscopy are often weak and difficult to detect. Acoustic cells can be used to amplify the signal, but they need to be designed with sensitivity in mind.

Is Meshing Run in Parallel in COMSOL Multiphysics®?
Meshing, an integral part of modeling in COMSOL Multiphysics®, can take up a lot of time and resources. Parallelized meshing speeds things up by distributing the meshing of domains on more cores.

Introduction to Numerical Integration and Gauss Points
In this comprehensive blog post, we go over the theory behind numerical integration, Gaussian quadrature, Gauss points, weak contributions, and much more.
