ABB Minimizes Transformer Hum with Simulation
We rely on power transformers for everyday tasks, but these devices also create a loud buzzing or humming noise. This sound comes from vibrations in different parts of the transformer and is impossible to eliminate completely. To reduce the noise, a team of engineers at ABB Corporate Research Center simulated the acoustic, electromagnetic, and mechanical behavior in their transformer systems with the COMSOL Multiphysics® software.
Streamline Your Simulation Workflow with Named Selections
When you are creating a model, it can sometimes be difficult to keep track of all the parts in the geometry, including the conditions or constraints that apply to each section. This is especially true when dealing with large, complex geometries and multiple physics interfaces. In COMSOL Multiphysics, tools like named selections help maintain your model setup and streamline your workflow. Here’s a look at three tutorial videos demonstrating how to create and utilize Explicit, coordinate-based, Boolean, and adjacent selections.
Using Apps to Optimize Induction Heating for Food Processing
Modern food processing techniques are constantly being analyzed and improved. To evaluate the efficiency of such techniques and the equipment that they utilize, researchers and engineers can turn to simulation tools like COMSOL Multiphysics. Numerical modeling apps are helping to bring this simulation power to a wider audience, accelerating the optimization of such processes along the way. Let’s see how this applies to the analysis of induction heating for food processing.
How to Build a Parameterized Archimedean Spiral Geometry
Archimedean spirals are often used in the analysis of inductor coils, spiral heat exchangers, and microfluidic devices. Today, we will demonstrate how to build an Archimedean spiral using analytic equations and their derivatives to define a set of spiral curves. Based on these curves, we will then create a 2D geometry with specific thickness, extruding it to a full 3D geometry.
University of Buffalo Fosters Industrial Innovation with Apps
As technology evolves, the demand for devices with greater features and functionality emerges. Of course, this means that the designs themselves become more intricate and complex. Simulation offers an efficient route to analyzing and optimizing such devices, prompting further industrial innovation along the way. Today, we’ll take a look at how a team from University of Buffalo designed multiphysics models and simulation apps to spread modeling expertise to a broader range of industries.
Evaluating an Insulin Micropump Design for Treating Diabetes
In any form of treatment, it is always desirable to minimize the level of discomfort that the treatment process causes patients, while ensuring overall safety and effectiveness. For diabetes patients, insulin injections remain an important form of treatment, but the process itself can be painful. With the help of multiphysics simulation, a team of researchers from the University of Ontario Institute of Technology sought to develop a MEMS-based micropump that could administer insulin injections in a safe and painless way.
How to Dynamically Modify Geometries in Simulation Apps
The Application Builder is a powerful tool for transforming models into customized, easy-to-use apps. An app’s intuitive user interface (UI) not only gives you control over simulation inputs and geometric parameters, but it also enables you to program the app to perform complex operations. Today, we’ll demonstrate how to create an app that allows you to dynamically create or modify geometry parts and apply appropriate physical specifications and mesh, all thanks to the power and flexibility of the Method Editor.
Enhance Your Visualization Plots with 6 New Color Tables
You’ve generated your simulation results and you want to communicate your findings with other people. To do so clearly and effectively, you will need to create easy-to-understand, eye-catching visualizations. Therefore, as of COMSOL Multiphysics® software version 5.2a, you now have six new color tables to further enhance your postprocessing. Let’s learn about the inspiration behind these color tables and take a look at a few specific use cases.
