A Multidisciplinary Approach to Electronics Design
Sharp is a powerhouse in the electronics industry, involved in televisions, liquid crystal displays, LED lighting systems, solar cells, multi-function business machines, and many other electronics-based products. One of a global network of Sharp R&D laboratories, Sharp Laboratories of Europe (located in Oxford, England), has been busy researching and developing LED lighting, display technology, microfluidic lab-on-a-chip, and energy systems for incorporation into Sharp’s products.
Video: 2D Models from Cross Sections of 3D Geometries
A while back, I blogged about a new feature made available in COMSOL Multiphysics 4.3b, the ability to create 2D models from the cross sections of 3D geometries. We are so excited for this new feature that we decided to make a video showing you how easy it is to use.
Mesh Refinement for Wave Problems
This week we are happy to have Kyle Koppenhoefer of AltaSim Technologies as a guest blogger. As COMSOL Certified Consultants, AltaSim can share valuable insights into using the software — today on the topic of meshing wave problems. As part of our efforts to assist COMSOL users in performing high-quality analysis, we recently used our bi-monthly email to remind users to include twelve degrees of freedom per wavelength when meshing wave problems. This article builds on our previous advice. Wave-type […]
Molecular Flow Module: Simulate Rarefied Gas Flows in Vacuum Systems
Vacuum technology has many important applications, from semiconductor device and MEMS fabrication, to vacuum coatings for corrosion protection, optical films, and metallization. The new Molecular Flow Module provides vacuum engineers with previously unavailable tools for modeling gas flows within vacuum systems.
Multiphysics Simulations inside the Autodesk® Inventor® User Interface
Starting with the release of COMSOL Multiphysics® 4.3b you can work with multiphysics simulations right from the user interface of the Autodesk® Inventor® CAD system. Called the One Window interface, this functionality is available with LiveLink™ for Inventor®. The result of the work by our external interfaces and integrations development team, the One Window interface, is a completely new environment for simulations that are embedded in the Inventor® user interface. It contains the Model Builder, Settings, and all other views […]
Simulate Mechanical Systems with the Multibody Dynamics Module
The new Multibody Dynamics Module provides engineers with an advanced set of tools to design and optimize mechanical systems to reduce product development costs. This module enables simulation of an assembly of flexible and rigid bodies, along with physical phenomena like structural, heat, electrical, and others. One of the key capabilities included in this module is an easier and faster way of building connections between different bodies using various types of predefined Joints. The objective of multibody analysis is to […]
Sweep Your Meshes with Ease
Swept meshing is a geometry discretization technique available in COMSOL Multiphysics for specific types of geometries, including thin geometries, geometries with bends, and models with little or no variation in a specific direction. A swept mesh starts at a source boundary and sweeps along to a specified destination boundary. In previous versions of COMSOL Multiphysics, the source and destination boundaries generally needed to be specified by the user. However, in the latest release, COMSOL Multiphysics version 4.3b, the swept mesh […]
The Graphene Revolution: Part 5
In a paper titled “Choosing a Gate Dielectric for Graphene Based Transistors“, the applications of a semiconducting form of graphene are examined. As we have seen before, single-layer graphene is not a semiconductor, it is a zero bandgap conductor (a semimetal). Efforts are well underway to introduce bandgaps to graphene, which would make it semiconducting with a room temperature mobility an order of magnitude higher than silicon. The race is already underway to find applications for such a material once […]
