## Advanced Visualization Techniques in Postprocessing

Postprocessing | Posted on March 22nd, 2013 by

Looking for ways to cut down on the time and computer memory required to run your simulation? Does your model exhibit some form of symmetry — axial symmetry, lines or planes of symmetry, or antisymmetry for example? Or perhaps your model exhibits periodicity? If you answered yes to those questions, you’re in luck. You can model symmetry or periodicity in COMSOL Multiphysics easily by either using a 1D or 2D axisymmetric dimensional simulation or by incorporating boundary conditions that represent a symmetry or periodic condition.

## CFD Postprocessing

Postprocessing | Posted on January 14th, 2013 by

We have written several blog posts on postprocessing already, but none detailing postprocessing for CFD. Postprocessing has always been an important part of my teachings, as you learn how to use COMSOL Multiphysics while also gaining insight into the physics at hand. I would like to share with you part of the classwork I proposed when teaching a CFD training course not long ago.

## Video Tutorial: Adding Data from Excel® to a COMSOL Model

Heat Transfer | Posted on January 1st, 2013 by

We have been adding a lot of content to our website lately, involving the new LiveLink™ for Excel®. It’s a welcomed addition to the COMSOL family and we can’t stop talking about it. We want to make sure everyone knows about the strengths of LiveLink™ for Excel®, and how it can make your modeling easier, more efficient, and more powerful. Now we have another video for you, and this one demonstrates how to add data from Excel® to a COMSOL model.

## Modeling Static Mixers

Fluid | Posted on November 9th, 2012 by

A mixer that doesn’t move may sound like an oxymoron, but it’s not. Used in various chemical species transport applications, static mixers are inexpensive, accurate, and versatile. Still, there is always room for improvement. Optimizing the design of static mixers calls for computer modeling, but traditional CFD methods may not be the best way to model these mixers. How do these motionless mixers work and how can their performance be simulated?

## Video Tutorial: Basic Visualization

Postprocessing | Posted on November 2nd, 2012 by

I’m back on the blog with the latest installment in the Postprocessing and Visualization Videos series. The two-part video shown here covers “Basic Visualization”. Chapter 1 and 2 will give you an overview of COMSOL’s visualization tools so that you can optimize how you view your model, both while setting up your physics and while postprocessing. I explain two tricks in the video that I’d like to draw your attention to in particular.

## COMSOL now Supports the New W5000 and W7000 AMD FirePro™ Graphics Cards

Postprocessing | Posted on October 25th, 2012 by

AMD has a new architecture for their graphics cards called Graphics Core Next (GCN). Perfect for compute-intensive applications, the new W-series are optimized and guarantee ultimate performance for visualizing and working with geometries and complex models. COMSOL is proud to announce that we now support the new W5000 and W7000 AMD FirePro™ Graphics Cards. This continues the partnership we have with AMD that I highlighted in a previous blog post about AMD FirePro graphics cards.

## Video Tutorial: Create 1D Plots in COMSOL

Postprocessing | Posted on August 28th, 2012 by

Would you like to plot your own expressions in COMSOL? Have you ever wanted the power to measure parameters from your virtual model at whatever point you’d like, just as you would in a physical model? This new postprocessing tutorial video duo explains how to create 1D plots in COMSOL.

## A Better File Format for 3D Printing to Replace STL?

Postprocessing | Posted on August 8th, 2012 by

I have previously blogged about 3D printing and how it would be great if you could go from model to product in one step. Now it seems as though the Stereolithography (STL) file format is reaching its limits for being useful as a standard for this type of application. The printers themselves, and what they are capable of, are outstripping the abilities of the file formats to support their new capabilities. Moves are being made to develop a better file format for 3D printing, and the American Society for Testing and Materials (ASTM) is throwing its weight behind this.

## Video Tutorial: Creating and Customizing Plots in COMSOL

Postprocessing | Posted on August 7th, 2012 by

As promised, I’m back to introduce to you the second tutorial video in the new postprocessing blog series. This video covers the basics of creating plots, including some useful ways you can tweak and customize your plots. For example, have you ever wanted to improve the resolution of a plot, add or modify titles and axis labels, standardize the color bars over multiple graphs in one plot group, modify a deformation plot’s scaling, or view multiple plots in the COMSOL GUI simultaneously? All of these features are explained demo-style in this video on Creating and Customizing Plots in COMSOL:

## Video Tutorial: Functional Overview of Postprocessing

Postprocessing | Posted on July 31st, 2012 by

Are you getting the most out of your simulations? There’s a wealth of options for creating plots and animations and for computing and exporting data in COMSOL, odds are you will find some neat features here. We want to get you off to a good start, so I’ve begun a series of tutorial videos covering a wide variety of topics in postprocessing. This tutorial series is suited for new and experienced users alike. You will get to learn the basics while picking up new tips and tricks in COMSOL’s latest release at the same time. For example, did you know that you can now create a comprehensive report of your simulation as a Microsoft Word document?
