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.

Sensing the Bio in Biosensor Design with a Simulation App

May 12, 2015

Biosensors are the workhorses of the analytical tools used for detailed mechanistic understanding at the molecular level of biological systems. The applications of these analysis tools are countless for the detection of biomolecules in the pharmaceutical, health care, and food industries; agriculture; environmental technologies; and in general for research of biological systems. The biosensor demo app is a good example of an application where non-experts can benefit from accurate multiphysics simulations.

Simulating Analog-to-Digital Microdroplet Dispensers for LOCs

May 11, 2015

Microfluidic biochips have a variety of applications and are valued for their low cost, fast response time, and high efficiency. In the paper “Design and Simulation of High-Throughput Microfluidic Droplet Dispenser for Lab-on-a-Chip Applications”, which was presented at the COMSOL Conference 2014 Boston, researchers designed a microfluidic biochip with an analog-to-digital converter. They used COMSOL Multiphysics software to understand the mechanism of the device and verify its function.

How to Create a Simulation App: Horn Antenna Demo

May 4, 2015

What if you could enable non-experts to run your multiphysics simulations on their own? You would save time, for sure, and they would get easy access to your expertise. Turning your simulations into apps with customized and easy-to-use interfaces is now a reality. Here, I will explain why you should start creating apps and how to go about it. We’ll use the new Corrugated Circular Horn Antenna Simulator demo app to guide us.

Using Deformations to Visualize Physical Motion

April 28, 2015

When simulating acoustic waves, vibrating mechanical hardware, or fluid in a channel — just to name a few applications — you may be interested in visualizing the movement or shape change in a device. Postprocessing and visualization can help enhance your understanding of simulation results, and using plots to illustrate physical motion allows you to put everything into perspective. Deformations are a great way to accomplish this.

Implementing the Weak Form with a COMSOL App

April 16, 2015

Previously in our weak form series, we discretized the weak form equation to obtain a matrix equation to solve for the unknown coefficients in our simple example problem. Following the same procedure as in this previous blog post, we will implement the equation in the COMSOL Multiphysics® software with additional steps included to examine the matrices. We will find it more convenient to use a COMSOL® software application to display all relevant matrices at once, arranged logically on one screen.
