The Boltzmann Equation, Two-Term Approximation Interface

February 24, 2022

When modeling plasma, you sometimes want to define the electron transport properties as a function of the electron energy. The Boltzmann Equation, Two-Term Approximation interface does just that.

Micromagnetic Simulation with COMSOL Multiphysics®

September 24, 2021

A guest blogger from Fudan University in China used the Physics Builder in COMSOL Multiphysics to create a “Micromagnetics Module” for performing micromagnetic simulations.

How to Analyze Turbomolecular Pumps with COMSOL Multiphysics®

January 12, 2021

Modeling gas flow in a turbomolecular pump calls for specialized numerical methods, because at such low pressures, the gas molecules rarely collide with each other.

Computational Electromagnetics Modeling: Which Module to Use?

July 28, 2020

If you work with a particular electromagnetic device or application area, you might be wondering which module in the COMSOL product suite is right for you. Keep reading for a comprehensive intro.

Global Modeling of a Non-Maxwellian Discharge in COMSOL®

November 19, 2018

Keep reading for a demonstration of how to model a non-Maxwellian discharge with the Boltzmann equation in the two-term approximation using COMSOL Multiphysics®.

Introduction to Plasma Modeling with Non-Maxwellian EEDFs

July 5, 2017

Modeling plasma that has a non-Maxwellian electron energy distribution function (EEDF) results in a catch-22. However, this issue can be overcome by building a simulation application.

A Multilevel Approach to Modeling Planar Discharge in CO2 Lasers

April 24, 2017
