Two Methods for Modeling Free Surfaces in COMSOL Multiphysics®

May 15, 2018

We take you through 2 methods for modeling free surfaces in the COMSOL® software: the level set and phase field methods. Learn how to use each method and their benefits.

Using the Algebraic Multigrid (AMG) Method for Large CFD Simulations

March 26, 2018

There’s an ideal method for solving large CFD simulations that involve complex geometries. It’s called the algebraic multigrid (AMG) method, and you can learn all about it here.

Calculating Thermodynamic Properties for Liquids and Gases

December 26, 2017

The Chemical Reaction Engineering Module includes a built-in database of over a dozen thermodynamic properties, making it easier to set up your transport and reaction models. Details here.

Why Should I Use Automatic Wall Treatment for My CFD Modeling?

June 26, 2017

The automatic wall treatment functionality enables you to use low Reynolds number models for a wider range of CFD problems, but there are some factors to consider before implementing the feature.

How to Use the v2-f Turbulence Model in the CFD Module

May 15, 2017

The v2-f turbulence model is an effective option for simulating highly nonlinear turbulent flow problems with both the accuracy and robustness of other, more limiting methods.

Fat-Washing Cocktails on an Industrial Scale

February 2, 2017

Bacon-flavored vodka? Pecan-infused bourbon? The fat-washing process extracts the flavors from fat and dissolves it into alcohol, and it can even be scaled up to an industrial level.

Introduction to Modeling Natural Convection in COMSOL Multiphysics®

December 23, 2016

Natural convection is a phenomenon found in many science and engineering applications, such as electronics cooling, indoor climate systems, and environmental transport problems. The CFD and Heat Transfer modules in version 5.2a of the COMSOL Multiphysics® software include functionality that makes it easier to set up and solve natural convection problems. In this blog post, we give an overview of natural convection, the new functionality, and some of the difficulties that we may stumble upon when modeling natural convection.

New Reacting Flow Multiphysics Interface Delivers Greater Flexibility

September 9, 2016

In recent versions of the COMSOL Multiphysics® software, we’ve added several new multiphysics interfaces that include the constituent interfaces as separate physics interfaces, with the couplings predefined in the model tree’s Multiphysics node. This provides you with the best of both worlds, combining the flexibility of the constituent physics interfaces and the user-friendly nature of the predefined multiphysics couplings. The latest version of COMSOL Multiphysics® — version 5.2a — is no exception with the new Reacting Flow multiphysics interface.
