Digital Twins and Model-Based Battery Design

Ed Fontes February 20, 2019

By combining high-fidelity multiphysics models with lightweight models and measured data, engineers can create digital twins to understand, predict, optimize, and control real-world systems.

Digital Twins: Not Just Hype

Ed Fontes February 19, 2019

The term “digital twin” has been called everything from just hype to a revolutionary concept. We use a jet engine example to explain the concept of digital twins and how simulation fits in.

FEM vs. FVM

Ed Fontes November 29, 2018

Finite element methods, finite volume methods, or a hybrid approach: Which is the best choice for CFD? It depends on the fluid flow problem you’re trying to solve.

Does It Matter Which Ball the FIFA World Cup™ Teams Practiced With?

Ed Fontes June 6, 2018

In an attempt to determine what type of soccer ball is best to prepare for the FIFA World Cup™, we set up a backyard experiment involving a leaf blower, level, and a few soccer balls.

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

Ed Fontes 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

Ed Fontes 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®

Ed Fontes 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

Ed Fontes 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

Ed Fontes 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?

Ed Fontes 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

Ed Fontes 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.
