Modeling Laser-Material Interactions in COMSOL Multiphysics

June 22, 2015

A question that we are asked all of the time is if COMSOL Multiphysics can model laser-material interactions and heating. The answer, of course, depends on exactly what type of problem you want to solve, as different modeling techniques are appropriate for different problems. Today, we will discuss various approaches for simulating the heating of materials illuminated by laser light.

App: Evaluating the Design of an Ion Implanter

June 17, 2015

The semiconductor industry uses ion implanters to implant dopants into wafers. To optimize the design of these devices, engineers need to quickly and easily test a wide range of parameters. Simulation apps help streamline the design process of ion implanters by sharing the capabilities of a simple and fully customizable interface with colleagues who don’t have a simulation background. Here, we introduce you to our Ion Implanter Evaluator demo app.

App: Studying a Concentric Tube Heat Exchanger’s Dimensions

June 10, 2015

By design, heat exchangers transfer heat from one source to another. When analyzing the efficiency of this heat transfer, it is important to consider the impact of the system’s dimensions. Simulation offers a simplified approach to testing the performance of various designs. With simulation apps, you can now bring this power into the hands of those who are not simulation experts. Let’s get started by exploring the Concentric Tube Heat Exchanger Dimensioning Tool demo app.

Useful Tools for Postprocessing in COMSOL Multiphysics

June 8, 2015

In recent posts, we have covered a variety of plot types used for postprocessing simulation results in COMSOL Multiphysics and the ways that they can help you understand and share your results. Now let’s take a look at some tricks to simplify work in the graphics window.

Optimizing Heat Sink Designs with a Simulation App

June 4, 2015

Heat sinks are components designed to cool off devices by dissipating heat. They can be used passively or in active cooling systems combined with fans for example. When optimizing heat sink designs, you can turn to simulation for guidance. But what if you could simplify the design process by embedding your model in an app? You can — and the Heat Sink with Fins demo app is here to get you started.

Using a Simulation App to Evaluate Fatigue Life in a Frame

May 28, 2015

Simulating fatigue offers valuable insight into how stress can affect the longevity of a structure and its components. This can help identify potential design problems and pave the way for the development of a safer structure. Arriving at this solution, however, often requires running several simulations to test different scenarios. Our Frame Fatigue Life demo app demonstrates how simulation apps can save you time and energy in evaluating the impact of fatigue.

App: Improving the Payload Capacity of a Truck-Mounted Crane

May 21, 2015

Truck-mounted cranes are designed to handle heavy loads. With this in mind, manufacturers and engineers look to optimize the machine’s payload, or carrying, capacity. Simulation apps can help expedite the optimization process by extending simulation capabilities into the hands of those who are not experts in simulation through a customized and intuitive interface. Our Truck Mounted Crane Analyzer demo app shows the benefits of this approach.

Creating a Wavelength Tunable LED Simulation App

May 18, 2015

Thanks to the Semiconductor Module and the Application Builder, developing custom optoelectronic simulation apps has never been easier. In this blog post, we show you how to turn a model of an LED device into a user-friendly application that can be used to assess the impact of different designs on the LED’s emission characteristics and performance. We also demonstrate the use of custom methods to manipulate the solution data, enabling the easy creation of bespoke analysis tools.
