Apps: How to Use the Editor Tools and Record Code Features

Andrew Griesmer | December 21, 2015

As you are learning to create apps in the Application Builder, we want you to take advantage of all of the tools that are available to you. The video featured here introduces you to the Editor Tools, Model Data Access, and Record Code features and demonstrates how to use them. To do so, we add a button to our app that can switch the type of plot shown in the graphics window.

Reinforced concrete beams are commonly used in modern construction due to their strength and durability. To avoid failure, each new beam design needs to be optimized and tested for safety. Building physical prototypes to test every design modification can be a long and costly endeavor. Simulation apps offer a solution, saving time and money as they bring simulation power into the hands of more people. Explore the benefits of this approach with our Parameterized Concrete Beam demo app.

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.

When the loudspeaker was first introduced, it fascinated listeners by translating electricity into amplified sound. Since that time, the device continues to be recognized for its innovative properties, while undergoing improvements and finding new uses. On this day, which marks 100 years since the first public display of a loudspeaker, we explore the device’s rich history and simulation’s role in advancing its design.

In the Application Builder, included with COMSOL Multiphysics version 5.2, the new Editor Tools window makes it possible to create simulation apps with a lot fewer clicks of the mouse. In this blog post, we will demonstrate how to create an app with Editor Tools using a simple simulation example, as well as show how to perform common user interface creation tasks more easily.

When developing a new product or functionality, the first step is typically to understand the functional properties in isolation. To achieve reliable and accurate predictions via mathematical modeling, it is essential that the critical components, test setup, and boundary conditions are specified in great detail. Most engineers, however, would prefer to focus on the critical components rather than “irrelevant” boundary conditions. New impedance boundary conditions in the Acoustics Module of COMSOL Multiphysics help to close this gap.

In COMSOL Multiphysics version 5.2, the CFD and Microfluidics modules include a new fluid flow interface for modeling separated three-phase flow. The model behind this fluid flow interface accounts for surface tension between each pair of fluids, contact angles with the walls, as well as the density and viscosity of each of the fluids. The phase field method computes the shape of the interfaces between the three phases and also accounts for interactions with walls.

The demand for better performance and increased accuracy in touchscreen devices is growing. Simulation, a fast and cost-effective approach to product development, helps to meet this goal. With each design modification, colleagues will typically rely on you to run simulation tests, awaiting your feedback before reaching out to customers. As researchers at Parade Technologies (formerly Cypress Semiconductor) have discovered, creating apps and distributing them to colleagues is a valuable way to save time and more effectively communicate with customers.

When a vehicle rapidly accelerates or brakes, the liquid within its tanks moves back and forth, producing dynamic forces and splashing — a process known as sloshing. Using COMSOL Multiphysics, a team of simulation engineers at IAV found that these forces could be efficiently reduced through the numerical optimization of the internal wave breakers, without impeding the fluid supply. Today, we’ll explore this force reduction approach and the principles behind it with our own tank geometry example.

Microchannels are versatile structures that can be used for thermal management. One way to optimize heat transfer within such systems is by adding a pin fin heat sink to the microchannel configuration. Applying this approach, a team of researchers created a novel pin fin design, analyzing its heat transfer efficiency with COMSOL Multiphysics. They presented their innovative work at the COMSOL Conference 2015 Boston.

Healthcare-associated infections (HAI) affect millions of people around the globe. While the most common cause of HAI is direct contact with the source, airborne bacteria may also play a role in patient infections. To prevent airborne infection and make hospital clean rooms safer, it’s important to design efficient ventilation systems. As an added benefit, efficient ventilation designs also lead to lower energy-related costs. The first step to a better design is CFD modeling.
