Modeling a Surface Micromachined Accelerometer

Bridget Cunningham | December 23, 2014

Surface micromachining is a process used to manufacture MEMS devices, which includes accelerometers. In this blog post, we model the electric field and forces within an accelerometer as well as highlight a new geometry feature available in COMSOL Multiphysics version 5.0.

The COMSOL Conference made its annual stop in Bangalore a few weeks ago. Engineers and academics from across the country gathered to participate in the exciting two-day event. Here are some photos from the COMSOL Conference 2014 Bangalore.

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.

Charge exchange cells are often used as a way to obtain neutralized beams of energetic particles. In this blog post, we introduce a model of a simple charge exchange cell and analyze its neutralization efficiency.

Among its neighboring buildings on the Las Vegas strip, the Vdara® hotel can be identified by its unique crescent-shaped design. While visually appealing, this architectural element became an area of concern as it contributed to the development of a caustic surface on the hotel’s pool deck. As a result, guests at particular locations experienced severe sunburns at certain days and times of the year. Here, we model the generation of a caustic surface in the case of the Vdara® hotel.

With the release of the Application Builder, we also bring you tutorial apps for getting started. You can find these applications both within the Application Library in the software and online in the Model Gallery. This is your resource on where to find the tutorials, including how to run the Application Library update.

The COMSOL Conference 2014 Bangalore brought together many users from various parts of the world, giving them the opportunity to present their work and ideas, network, and socialize. All of the posters and presentations presented at the conference were fantastic and truly deserving of recognition. The program committee was faced with difficult decisions in selecting the best papers and posters from each category. Here are this year’s winners.

The printed circuit board (PCB) is the heart of almost any electronic product, carrying the components and copper wires supporting its functionality. The manufacture often involves electroplating, a process that can vary between designs. This leaves you, the engineer behind its simulation and optimization, constantly creating new models. What if you could push much of this work onto the designers, engineers, and technicians behind its design and manufacture, having them run their own electroplating simulations for PCBs? See how here.

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.

The Membrane interface has undergone a number of changes with the release of COMSOL Multiphysics version 5.0. This includes a restructured menu, new feature nodes, improvements to the Linear Elastic Material model, and support for the Hyperelastic Material model. You might remember the Nonlinear Structural Materials model Inflation of a Spherical Rubber Balloon. We have now rebuilt it using the Membrane interface. I will discuss these changes and the new model in today’s blog post.

Here’s a question for all you electromagnetics-focused simulation engineers out there: Have you ever looked in envy at your structural, fluid, and chemical counterparts as they mesh their models with the click of a button, while you struggle to mesh your infinite elements or perfectly matched layers? Well, now you too can enjoy automatic meshing with a click (or two). Let me show you how.
