Ray Tracing in Monochromators and Spectrometers

December 25, 2014

Optical devices such as monochromators and spectrometers can be used to separate polychromatic, or multicolored, light into separate colors. These devices have many applications in diverse areas that range from chemistry to astronomy. Using built-in tools in the Ray Optics Module, it is possible to model the separation of electromagnetic rays at different frequencies with a monochromator or spectrometer as well as analyze the resolution of such devices.

Maximum Evaluations on Parallel Sections

December 24, 2014

In a previous blog entry, we shared a postprocessing technique for creating an animation by combining parallel slices in a 3D steady-state model. Today, we will look at another postprocessing trick: how to evaluate and plot the maximum (or the minimum, average, or integration) value of any variable at various parallel sections along the axial coordinate.

Modeling a Surface Micromachined Accelerometer

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.

December 22, 2014

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.

COMSOL Conference 2014 Bangalore Award Winners

December 19, 2014

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.

Fillet Away Your Electromagnetic Field Singularities

December 18, 2014

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 this a problem? If so, what can you do about it? Read on to find out.

Electroplating Simulations for Printed Circuit Board Designers

December 17, 2014

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.

Modeling Beam Neutralization with a Charge Exchange Cell

December 16, 2014

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.
