AltaSim Designs and Deploys Apps to Spread Simulation Power

Brianne Costa | November 23, 2015

At the COMSOL Conference 2015 Boston, Jeff Crompton from AltaSim Technologies — a COMSOL Certified Consultant — spoke about building, sharing, and deploying apps and what this means for the future of simulation. The team at AltaSim develops apps for a variety of purposes, from analyzing power electronics to additive manufacturing technologies. While some apps are deployed for commercial use, others are customized to meet the specific needs of companies. See how AltaSim is making simulation more accessible with apps.

Today, we introduce guest blogger Bernd Baumann, who shares insight into optimizing the performance of metal-halide lamps with simulation, with input from his colleague Joerg Schwieger. With the help of COMSOL Multiphysics, we investigated the impact of acoustic resonances and the related acoustic streaming field on the operation of metal-halide discharge lamps. To our surprise, we found that the lamps exhibit behaviors that are similar to a well-known mechanical system — the forced Duffing oscillator with a softening spring.

Today, we welcome Lars Fromme back to the blog — this time as a guest blogger from the FH Bielefeld University of Applied Sciences. Working with loud machines is an occupational safety issue in the modern world. To keep workers safe, we can design low-cost solutions to control the noise with the help of simulation. Researchers at the FH Bielefeld University of Applied Sciences set out to do just that by simulating acoustic transfer paths with COMSOL Multiphysics simulation software.

Keeping buildings cool in the summer and warm in the winter is a major drain on energy resources. In search of a more cost-effective and energy-efficient way to heat and cool buildings, researchers at Fraunhofer ISE continuously work to develop adsorption-based systems that run on solar energy, natural gas, and industrial waste. Using COMSOL Multiphysics® simulation software, the team investigates the adsorption process, heat exchanger design, and numerous other systems that affect their innovative developments in adsorption technology.

In our Acoustophoretic Force blog series, we have discussed the nature of acoustic radiation force and different ways to compute this force in the COMSOL Multiphysics® software. Today, we will introduce you to a related phenomenon, acoustic orbital angular momentum, and demonstrate how to model it.

This past July, I had the pleasure of attending the 22nd International Congress on Sound and Vibration. In addition to running the COMSOL vendor booth with my Italian colleague Gabriele, I was also a presenter at the event. My presentation was based on a paper I wrote with Henrik Bruus and Jonas Karlsen that focuses on how to determine acoustic radiation forces including thermoviscous effects. Let’s explore acoustophoretic effects in greater detail and the research findings highlighted in my presentation.

Doctors can more effectively treat skin cancer when skin tumors are detected early. While visual examinations are typically used to identify such tumors, noninvasive tools like dielectric probes offer another approach. With COMSOL Multiphysics, we analyze the functionality and safety of a dielectric probe used for skin cancer diagnosis.

Heat has a powerful effect on the operation and lifespan of electronic devices. Introducing components like heat sinks within these electronic systems helps maintain cooler temperatures and promotes healthy performance. As we demonstrate with our disk-stack heat sink example, simulation is a powerful tool for analyzing the efficiency of heat sink designs.

As a technical support engineer, one of the most common technical questions I receive is: “How can I compute the mass conservation of a fluid flow simulation or the energy balance of a conjugate heat transfer simulation?” This is often requested to investigate and ensure a simulation’s accuracy. Here, I will demonstrate how to perform these calculations in COMSOL Multiphysics and introduce some of the predefined variables available for postprocessing the energy rate terms of the energy balance equation.

Arteries are designed to carry blood containing oxygen and nutrients from the heart to other areas of the body. Studying this biological soft tissue from a mechanical standpoint requires a reliable model that can fully describe the arteries’ anisotropic nonlinear response. Our tutorial of arterial wall mechanics illustrates such a design.

In an operating nuclear reactor, complex and highly coupled physical phenomena occur. Analyzing such phenomena within these devices by conducting physical experiments is often difficult and sometimes impossible. Simulation offers a simplified approach to studying and optimizing nuclear reactor designs, saving time, money, and other resources.
