Improved Capabilities for Meshing with Tetrahedral Elements

September 27, 2016

In this blog post, we guide you through the process of generating a tetrahedral mesh for your COMSOL Multiphysics® models.

Improved Functionality and Tips for Importing STL and NASTRAN® Files

September 14, 2016

Learn how to import STL files originating from 3D scan sources and meshes in the NASTRAN® file format, as well as how to prepare them for analysis in COMSOL Multiphysics®.

Efficiently Mesh Your Model Geometry with Meshing Sequences

August 18, 2016

Meshing is one of the most memory-intensive steps when setting up and solving a finite element model. With a user-controlled mesh, you can reduce memory requirements while getting accurate results.

Exporting Meshes and Solutions Using the Application Builder

April 6, 2016

You can easily export mesh and analysis data from COMSOL Multiphysics® into a text file. How? Using the Application Builder. We show you how here.

Designing New Structures with Shape Optimization

December 29, 2015

Get a comprehensive background on using shape optimization to design new structures, with the example of a classical beam thickness problem.

Changing the Dimensions of a Model Using Shape Optimization

December 24, 2015

If your model has a single objective function to be improved, a set of geometric parameters to be changed, and a set of constraints, you can find the optimal structure without any remeshing.

How to Improve Your Paddle Stroke with Simulation

September 8, 2015

To take a closer look at a paddle stroke, for activities like canoeing and dragon boat racing, we set up a 2D model in COMSOL Multiphysics® and visualize the flow pattern around the paddle blade.

Deformed Mesh Interfaces: Rotations and Linear Translations

September 7, 2015

Using the finite element method often involves modeling solid objects that are rotating and translating within other domains. See how to use the deformed mesh interfaces to model these movements.
