Terminal Velocity, Drag Coefficients, and FIFA World Cup™ Predictions

June 1, 2018

Is it possible to predict the winners of the FIFA World Cup™? We forgo consulting a psychic and instead analyze the terminal velocity and drag coefficients of different balls with CFD simulation.

Modeling Free Surfaces in COMSOL Multiphysics® with Moving Mesh

May 31, 2018

You can model free liquid surfaces that do not undergo topology changes using moving mesh functionality in the COMSOL® software. Here’s a thorough guide on how to do so.

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.
