Graphene is a material with a strong presence — and impact — throughout the scientific community. Amongst its many uses, researchers are looking to graphene as a potential material solution within sensor designs for medical and biosensing applications. Today, we’ll explore the role of simulation in analyzing and optimizing a 3D multilayered graphene biosensor.

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.

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.

Whenever you are modeling the geometry that you will use for your COMSOL Multiphysics analysis, either with the native CAD creations tools in the COMSOL software or using another CAD system, you may end up with a geometry that has more features than you really need. Here, we will look at a set of features called Virtual Operations that will let you quickly and easily simplify any CAD data in preparation for modeling and meshing.

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.

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.

Have you been interested in learning how to create fillets on 3D designs or how to generate shell approximations of imported geometric objects? The latest version of the COMSOL Multiphysics® software includes the new Design Module, which provides these and other tools for easier and more advanced geometric modeling. This optional add-on also includes interoperability tools for the import and export of CAD designs. Let’s take a look in more detail at what you can do with these new features.
