To keep our antenna modeling process efficient and accurate, we should start with a simple geometry and then gradually add more complex features. The final simulation needs to include enough detail to accurately represent our design, while excluding elements that needlessly increase the computational cost. To demonstrate this, we look at an anechoic chamber example, which is used to characterize antenna performance, before examining how this process applies to several antenna examples available in the COMSOL Multiphysics® software.

Simulation is a powerful tool that enables you to obtain a holistic view of your design’s performance. While the physics you are studying may be complex, the environment in which you run such studies doesn’t have to be. This rationale has served as the logic behind continuously optimizing the user interface (UI) in the COMSOL Multiphysics® software for ease-of-use. Several tutorial videos, three of which are highlighted here, guide you on how to navigate the environment and utilize its tools.

In version 5.2 of COMSOL Server™, you can now launch apps much faster and configure the browser to run only one dedicated app. The Application Libraries, available in both COMSOL Multiphysics and COMSOL Server™, have been significantly updated with lots of examples for you to use and get inspired by when creating your own apps.

Today marks the release of COMSOL Multiphysics version 5.1. The latest COMSOL software version brings you 20 demo apps and many new features and functionality updates to numerous products. Here’s what you can expect after downloading version 5.1.

Nonlinear elastic materials present nonlinear stress-strain relationships even at infinitesimal strains — as opposed to hyperelastic materials, where stress-strain curves become significantly nonlinear at moderate to large strains. Important materials of this class are Ramberg-Osgood for modeling metals and other ductile materials and nonlinear soils models, such as the Duncan-Chang model.

Gears are devices that are widely used for the transmission of rotary motion from one shaft to another. Automobiles, electric motors, wind turbines, and other machines all require a gearbox in order to change their speed or torque. With the latest version of COMSOL Multiphysics® — version 5.2a — we bring you new gear modeling features and functionality, from components in the Parts Library to an array of tutorial models that illustrate potential applications.

When you are new to the COMSOL Multiphysics® simulation software, it is important to have access to resources that can help you get started with the software quickly. The installation and introduction manuals provide useful details, covering the basics of the modeling environment as well as some more advanced topics. Starting with version 5.2, the Simplified Chinese installation option now offers access to a number of these manuals in versions that are translated into Chinese.

Since we released version 5.0 of the COMSOL Multiphysics® software, you have the ability to create simulation apps — either starting from scratch or with a demo app from the Application Library. Today, we’ll introduce you to an app that can be used for understanding and optimizing mixer design and operation for a given fluid. The exemplified app models and simulates stirred tank mixers, which are used for reactors in the fine chemical, pharmaceutical, food, and consumer products industries.

We have created a video tutorial for those of you who are new to the COMSOL Multiphysics simulation software and need an introduction on how to use it. The video tutorial featured in this blog post shows you how to set up and run a simulation using COMSOL Multiphysics.

Have you been interested in learning how to create fillets on 3D designs or how to generate shell approximations of imported geometric objects? The latest version of the COMSOL Multiphysics® software includes the new Design Module, which provides these and other tools for easier and more advanced geometric modeling. This optional add-on also includes interoperability tools for the import and export of CAD designs. Let’s take a look in more detail at what you can do with these new features.
