Using the Help Tools in COMSOL Multiphysics® for Modeling Guidance

January 10, 2017

Within the COMSOL Multiphysics® software, you have access to Help tools to guide you along your modeling process, including the Help, Documentation, and Application Libraries windows.

How to Model an Anechoic Coating

January 5, 2017

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.

Designing Inkjet Printheads for Precise Material Deposition

January 4, 2017

The design of an inkjet printhead nozzle is important in order for the device to have precise material deposition, whether it is used in a 2D or 3D printer.

How to Assign Fluid Pressure in CFD Simulations

December 30, 2016

There are many ways to experimentally measure pressure in a fluid. When setting up a CFD model, it is important to use the correct definition of pressure for assigning boundary conditions and defining the material properties. Today, we’ll explain the difference between relative and absolute pressure, why the COMSOL Multiphysics® software solves CFD problems using relative pressure, and when to use each definition of pressure in your models.

Investigating Whale Behavior with an Innovative Tagging Device

December 29, 2016

When whales dive beneath the ocean’s surface, what do they do? To answer this question, wildlife researchers need to track these enormous creatures for long periods of time and across great distances. To help with this challenging task, there is a new long-lasting tracking device called the advanced dive behavior (ADB) tag. With this device, researchers can enhance their understanding of whales as well as investigate ocean conditions and the effects of climate change.
