How to Analyze Your SOLIDWORKS® Designs with an App

Lorant Olasz | November 24, 2016

For many years, it’s been possible to analyze synchronized CAD geometries in COMSOL Multiphysics® via the LiveLink™ interfacing products. But did you know that you can also incorporate this functionality into an easy-to-use simulation app? With an app, you can dynamically modify your geometry in a CAD program such as SOLIDWORKS® and use this information to analyze new product designs. Today, we will demonstrate how to do so, using the new Bike Frame Analyzer app as an example.

Food packaging is often composed of recycled materials, like newspapers or plastic, which may contain residual mineral oil inks. Traces of these potentially hazardous substances leftover from the recycled materials can migrate from the packaging to the stored food. To account for this, one research team developed a numerical model to analyze the migration patterns of mineral oil hydrocarbons for various packaging situations. Compared to experimental studies, their approach offers a more efficient and cost-effective way of optimizing food safety.

Bolometers have the ability to detect and measure the power of incident electromagnetic radiation. This allows them to be used in a range of technologies, from night vision cameras to far-reaching astronomy projects. Designing bolometers often requires devoting a lot of time and energy to the development phase, as these devices must be optimized for sensitivity and customized for their specific applications. To efficiently design bolometers with increased sensitivity, AltaSim Technologies utilized the simulation capabilities of COMSOL Multiphysics.

When using the finite element method, we often want to model solid objects that are rotating and translating within other domains. The deformed mesh interfaces in COMSOL Multiphysics can be used to model these movements. In this blog post, we will look at the modeling of large linear translations and rotations of domains within other domains, while introducing efficient modeling techniques for addressing such cases.

Magnetic bearings are used in many industrial applications, including power generation, petroleum refinement, turbo machinery, pumps, and flywheel energy storage systems. Unlike mechanical bearings, these types of bearings support moving loads without physical contact through magnetic levitation. Valued for their frictionless operation and ability to run without lubrication, magnetic bearings are a low-maintenance alternative to mechanical bearings — one with a longer lifespan. Learn how to calculate design parameters like magnetic forces, torque, and magnetic stiffness using COMSOL Multiphysics.

There are several different add-on modules to the COMSOL Multiphysics® software for working with external CAD and ECAD data. These modules allow both unidirectional and bidirectional data transfer between the COMSOL Multiphysics analysis tools and the CAD and ECAD software that you are using for design. In this blog post, we will cover the functionality of these various modules and describe why you may want to use them.

Architects cannot just be artists. A new building must not only be aesthetically pleasing but also structurally sound. In the design of modern buildings, great attention is paid to concepts such as environmental comfort and energy efficiency. With a range of physical problems to address in the transition from a building’s concept to a completed design, the 21st century architect may turn to multiphysics software.

In the past, I’ve received regular requests for the ability to check the view factors used by COMSOL Multiphysics. How accurate are they? What is the impact of a given parameter (mesh size, radiation resolution, etc.) on their accuracy? Good news: Version 5.0 provides new operators for postprocessing that correspond to the operators used to generate surface-to-surface equations. Allow me to demonstrate how to compute geometrical view factors.

No matter how much you refine the mesh at that corner in your geometry, the electromagnetic field that you are computing never seems to settle on a converged value. Is that a problem? If so, what can you do about it? Read on to find out.
