Optimizing an NIV Mask Design with Multiphysics Simulation

August 13, 2020

NIV masks offer a form of noninvasive monitoring and ventilation for COVID-19 patients, which lessens the need for ventilators and other mechanical respirators.

Exploring the 4 Basic Modes of Electrophoresis

August 6, 2020

Zone electrophoresis, moving-boundary electrophoresis, isotachophoresis, and isoelectric focusing. In most cases, the physics of new electrophoretic methods can be related back to these 4 modes.

Introducing the Porous Media Flow Module

June 11, 2020

From multiphase transport and non-Darcian flow to local thermal equilibrium and nonequilibrium, we discuss the advanced porous media flow modeling you can do with the Porous Media Flow Module.

Modeling Heat Transfer in Thin Layers via Layered Material Technology

May 15, 2020

We answer some questions you may have about the Layered Material functionality in the COMSOL® software: What does it do? How do you update existing models? How do simulations benefit from it?

6 Ways Engineers Are Using Simulation to Help the Environment

April 22, 2020

Energy-efficient buildings and appliances. Safe nuclear waste storage. Well-preserved freshwater lakes. These are just a few examples of how simulation is being used to help the environment.

Modeling and Simulation of Multiphase Flow in COMSOL®: Part 1

March 26, 2020

Multiphase flow can be modeled on scales ranging from fractions of microns to tens of meters. Get an overview of the dispersed and separated multiphase flow models for different types of flow.

Material Characterization by Means of Simulation

March 10, 2020

Carbon-based materials, such as synthetic specialty graphites, are found in many industries, including solar, semiconductor, car manufacturing, ceramics, and metallurgy.

Simulating the Carburization and Quenching of a Steel Gear

March 9, 2020

Gears are typically carburized and quenched to improve their fatigue durability and wear resistance. Simulation can help determine how these processes affect the gear’s residual stress state.
