Dielectrophoretic Separation

January 23, 2015

How can you use an electric field to control the movement of electrically neutral particles? This may sound impossible, but in this blog entry, we will see that the phenomenon of dielectrophoresis (DEP) can do the trick. We will learn how DEP can be applied to particle separation and demonstrate a very easy-to-use biomedical simulation app that is created with the Application Builder and run with COMSOL Server™.

Geometry Modeling in Simulation Apps

January 8, 2015

COMSOL applications created with the new Application Builder will make sophisticated simulations based on parameterized CAD models more accessible than ever before. A COMSOL application allows easy access to not only parameterized models but also completely different geometry configurations, such as a mixer with a variable number of impeller blades or a variable number of impellers. To make this easy for the application developer, we have made available cumulative selections and geometry parts. See how these tools work.

Electroplating Simulations for Printed Circuit Board Designers

December 17, 2014

The printed circuit board (PCB) is the heart of almost any electronic product, carrying the components and copper wires supporting its functionality. The manufacture often involves electroplating, a process that can vary between designs. This leaves you, the engineer behind its simulation and optimization, constantly creating new models. What if you could push much of this work onto the designers, engineers, and technicians behind its design and manufacture, having them run their own electroplating simulations for PCBs? See how here.

Where to Find Application Builder Tutorial Apps

December 10, 2014

With the release of the Application Builder, we also bring you tutorial apps for getting started. You can find these applications both within the Application Library in the software and online in the Model Gallery. This is your resource on where to find the tutorials, including how to run the Application Library update.

Creating an App for Modeling Flow Control in a Pipe Network

December 2, 2014

We just launched a new app for you to download from the Application Library update. This app is a dedicated tool for modeling the flow and pressure distribution inside a network of connected pipes. Engineers in semiconductor processing could use a tool like this to test a given design and ensure it will meet specification before prototyping the physical device. Here, I’ll give you some background info and walk you through how this app works.

Apps for Teaching Mathematical Modeling of Tubular Reactors

November 21, 2014

The Tubular Reactor application is a tool where students can model a nonideal tubular reactor, including radial and axial variations in temperature and composition, and investigate the impact of different operating conditions. It also exemplifies how teachers can build tailored interfaces for problems that challenge the students’ imagination. The model and exercise are originally described in Scott Fogler’s book Elements of Chemical Reaction Engineering. I wish I had access to this type of tool when I was a student!

The Tuning Fork Application

November 11, 2014

In order to make it easy to get started with the Application Builder, we included a few example applications in the Application Libraries of COMSOL Multiphysics version 5.0. This blog post will give you an overview of the Tuning Fork application and the structural vibration model that it is based on.
