Analyze the Hodgkin-Huxley Model with a Computational App

November 10, 2016

The Hodgkin-Huxley model is an advanced model for simulating action potential. We also go over how to use a computational app to streamline this type of analysis.

How to Use Acoustic Topology Optimization in Your Simulation Studies

November 3, 2016

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.
