The magnetostrictive effect causes magnetic materials to change their shape when a magnetic field is applied. Materials that exhibit such behavior are used in a range of devices, from loudspeakers to actuators. In order to analyze one type of device, a magnetostrictive transducer, researchers from ETREMA Products, Inc. performed single-physics and multiphysics simulation studies in COMSOL Multiphysics. See how the flexible nature of the software enabled the team to study various aspects of the device and optimize its overall design.

In various engineering fields, studying acoustic reflection and absorption is an important point of consideration. Simulation is a valuable tool for performing such analyses, helping to better explain how sound waves interact with their surrounding surfaces. Today, we’ll look at how the Application Builder is extending the reach of such simulation capabilities by using the example of acoustic reflections off a water-sediment interface.

When an electronic device overheats, it risks starting a fire. Cooling components, such as heat sinks, are designed to prevent this, but can’t always keep up with advancing technology. Simulation offers a solution by illustrating how well various heat sink designs conduct heat and how adding elements like manifold microchannels (MMC) improves performance. Today, we’ll explore how an MMC heat sink operates with simulation.

Shouldn’t the way you design a device be just as efficient as the device itself? When designing a centrifugal governor, the main goal is to increase the overall operation efficiency of an engine. With our Centrifugal Governor Simulator demo app, you can easily and quickly test a wide spectrum of parameters and physical studies to optimize the performance of the device. Today’s blog post offers insight.

Radiators, refrigerators, and geothermal pumps all need to efficiently extract heat from one fluid to another without mixing them. Among all of the different heat exchanger designs, finned pipes aim to increase the exchange surface between the content of a pipe and the exterior using fins. Finned pipes usually show a geometrical periodicity along the length, which we will take advantage of in this demo app to reduce computational costs.

Maximizing the efficiency of the learning process, while keeping students engaged — this is the common goal that professors hope to achieve in any course. In the realm of physics- and engineering-based courses, simulation apps are helping to strike such a balance by introducing students to complex concepts in a simplified format. Here, we’ll take a look at some of the innovative ways that university professors are utilizing apps within the classroom.

Lasers, focused beams of photons of a single wavelength, find use in a wide variety of applications today — from noninvasive surgeries and fiber optic communication to material processing and even DVD players. Let’s see how a research team from Lawrence Livermore National Laboratory (LLNL) used the power of multiphysics simulation to investigate laser-material interaction to avoid the damage of optics internal to high-power laser systems.

Why are the famous paintings on the walls of a Netherlands chapel deteriorating? To answer this question, researchers from the Eindhoven University of Technology used physical measurements and simulation to evaluate how rising moisture affects the chapel’s artwork. Today, we’ll see how their research helped provide a better understanding of the damage occurring within this cultural heritage site.

We’ve talked a lot on the blog about the different types of simulation apps that you can build. But did you know that you can create an app that plays sounds? The Organ Pipe Designer allows users to investigate the parameters behind an organ pipe configuration and then play the resulting sounds to really see — and hear — a design in action. Let’s learn more about the physics behind our underlying model and its transformation into an easy-to-use app.
