Part 1: Tips to Improve Simulation App Design and Structure

Ed Fontes | May 5, 2016

The Application Builder in the COMSOL Multiphysics® simulation software offers almost unlimited freedom in the design of apps. But as engineers, we need to balance our creativity with focus to avoid disorder in our simulation app design. In the first installment of a two-part blog series, we give a few guidelines that will help you create apps with a clear, streamlined design and structure.

Shouldn’t the way you design a device be just as efficient as the device itself? When designing a centrifugal governor, the main goal is to increase the overall operation efficiency of an engine. With our Centrifugal Governor Simulator demo app, you can easily and quickly test a wide spectrum of parameters and physical studies to optimize the performance of the device. Today’s blog post offers insight.

Magnetic gears are the contactless mechanisms for torque-speed conversion using permanent magnets or electromagnets. They are utilized in several renewable energy applications, increasing the speed of wind energy, ocean energy, and flywheel energy storage in order to match the specification of the electromagnetic generator. Unlike their mechanical counterparts, magnetic gears offer inherent overload protection, have high reliability due to frictionless operation, and require no lubrication. Today, we’ll discuss how to simulate magnetic gears in 2D and 3D with COMSOL Multiphysics.

We’ve talked a lot on the blog about the different types of simulation apps that you can build. But did you know that you can create an app that plays sounds? The Organ Pipe Designer allows users to investigate the parameters behind an organ pipe configuration and then play the resulting sounds to really see — and hear — a design in action. Let’s learn more about the physics behind our underlying model and its transformation into an easy-to-use app.
