How to Customize the COMSOL Desktop® and Use Keyboard Shortcuts

Magnus Ringh December 11, 2018

The COMSOL Desktop® is the integrated user environment for creating and managing simulations in the COMSOL Multiphysics® software. It includes the Model Builder window, model tree, Graphics window, as well as menus and toolbars with a multitude of modeling tools. In this blog post, we will show you how to customize the user interface and use a variety of keyboard shortcuts to get the most out of the modeling process.

Until the early 1900s, shock waves were an academic problem studied from a theoretical point of view only. Many great scientists, including Lord Rayleigh, worked on the field until the theory of inviscid shock waves was established in the 1920s. During World War II, this theory started to be applied, mostly to supersonic vehicles. To study shock waves, one important gas dynamic instrument is the shock tube, which is used to test supersonic and hypersonic flows and high-temperature gases.

Composite materials are heterogeneous materials composed of at least two integrated components. Among the different types of composite materials, layered composite materials are quite common and are widely used for aircraft, spacecraft, wind turbine, automobile, marine, buildings, and safety equipment use cases. The Composite Materials Module, add-on to the COMSOL Multiphysics® software, includes built-in features and functionality specifically designed for studying layered composite structures. Fiber-reinforced plastics, laminated plates, and sandwich panels are a few common examples of layered composite materials.

Heart failure is a global health concern, affecting millions of people and keeping them from their everyday lives. But what if there was a device that could keep patients’ hearts pumping and even improve their quality of life? In his keynote presentation at the COMSOL Conference 2018 Boston, Freddy Hansen from Abbott Laboratories discussed a heart pump that could do just that. If you missed his talk, you can watch a recording of the video and read a summary below.

There has always been a debate among engineers working with fluid flow about the suitability of finite element methods for CFD. Some engineers have a firm opinion about the superiority of finite volume methods compared to finite element methods. Is there a scientific support for this opinion? No, not in general. Different methods may be suitable for different problems. Let us see why.

Did you know that the COMSOL Multiphysics® software allows you to have different discontinuous meshes in neighboring domains? Although the usual default behavior of the software is to use aligned meshes, there are times when we might like to have discontinuous meshes, such as for modeling conjugate heat transfer. Let’s delve deeper into this topic and see how these meshes can save us time and memory in our initial model development with just a little bit more effort.

Material deposition is an essential ingredient in certain manufacturing processes, including welding and additive manufacturing. Say that you want to simulate such a manufacturing process. A challenge that you will face during the simulation is depositing material in a way that introduces it in a state of zero stress. Here, we look at the Activation functionality in the COMSOL Multiphysics® software and how it facilitates the simulation of material deposition.

To help understand the complicated universe we live in, we have compartmentalized physics phenomena into distinct disciplinary specializations. However, natural and engineering problems often cross these utilitarian borders. A major strength of the COMSOL Multiphysics® software is the ease with which such cross-disciplinary interactions, which we refer to as multiphysics interactions, can be accounted for. The COMSOL® software provides a plethora of built-in multiphysics couplings and even enables users to implement their own physics couplings.

During routine exams, eye care professionals look for common refractive errors like nearsightedness, farsightedness, and astigmatism. As patients age, doctors also look for presbyopia, a loss of the accommodative amplitude that results long-term in a complete loss of the near vision. The visual accommodation process is complex, and useful eye properties needed to improve diagnosis and presbyopia treatment are difficult to obtain. To address the problem of measuring the refractive index of the lens, researchers developed a reverse engineering technique […]

One of the core strengths of the COMSOL Multiphysics® software is the ability to easily define loads and constraints that move over time. There are actually several different ways in which this can be done, all within the core functionality of the software. In today’s blog post, we will guide you through three of these approaches.
