How Do Chladni Plates Make It Possible to Visualize Sound?
Can we “see” sound? Not directly, but we can come close. By changing our perspective, we can learn a lot about the nature of acoustics. One way to observe acoustics phenomena is by studying standing waves in a solid medium known as a Chladni plate. A special technique creates patterns on the plate that reveal sound’s physical…
Best Papers and Posters from the COMSOL Conference 2023 Munich
The COMSOL Conference 2023 returned in person this year in Munich, Germany, where the multiphysics simulation community formed new connections, learned about the latest advancements in the COMSOL Multiphysics® software, and drew inspiration from each other’s innovative work. During the three-day event, engineers, researchers, and scientists across industries showcased their findings through poster and slideshow presentations. Six teams earned special recognition for…
Solving the Superconductor Teaching Challenge with Apps
Why are superconductors and their applications such a challenging subject to teach? Francesco Grilli, a researcher and professor from the Karlsruhe Institute of Technology (KIT), has an idea as to why — and a solution to the problem. By building simulation applications and making them available in a web browser, Grilli helps present this complex topic in a captivating way…
Forming New Ideas with Generative Design in COMSOL®
Does a new design come from a person or a process? We may imagine that innovators envision a design and then pick up their pencils to bring their idea to life. Of course, designers and engineers today might not use pencils, and they might not have a final design idea in mind. Instead, some designers use a process that comes…
Why Do Golf Balls Have Dimples?
Dimples are famously crucial for the aerodynamic properties of a golf ball: They generate a turbulent flow that reduces the ball’s drag. However, doesn’t this sound counterintuitive? In general, smooth objects are more aerodynamic than rough ones. In today’s blog post, we will dig into the details of this apparent paradox; learn how to use this knowledge to model the…
Using COMSOL Multiphysics® for Teaching in Academia
Multiphysics modeling and simulation accelerates scientific research and increases the understanding of underlying phenomena, making it suited for use in engineering education. In this panel discussion, speakers Dr. Harold Ruiz from the University of Leicester and Dr. James Bowen from the Open University will share how they are using the COMSOL Multiphysics® software as an academic teaching aid.
Elevating the Performance of Ionization Gauges with Simulation
Semiconductor manufacturing, particle physics research, and other valuable processes occur in high-vacuum or ultra-high-vacuum (HV/UHV) conditions. To help develop a better ionization gauge for measuring pressure in HV/UHV environments, instrument manufacturer INFICON of Liechtenstein used multiphysics modeling to test and refine their impressive new design.

Using Different Physics Interfaces for RF Electromagnetic Heating Models
The COMSOL Multiphysics® software is well suited for modeling RF heating, where one needs to solve for both the electromagnetic fields and the temperature distribution over time. Although you might think that you need the RF Module for all types of problems involving RF heating, you can often use either the RF Module or the AC/DC Module, and you can use several…
Generating a Simulation Mesh of a Femur From 3D Data
Have you ever wondered how to create a simulation mesh out of data obtained by 3D imaging techniques? In this blog post, we will explain how to do so using the COMSOL Multiphysics® software. This topic expands on the theme of modeling irregular shapes, which we have explored in past blog posts. The processes we will discuss here are,…
