Today, we welcome Managing Director Dr. Alfred J. Svobodnik of Konzept-X GmbH, a COMSOL Certified Consultant and developer of multidisciplinary virtually optimized industrial design technology (M-voiD® technology). MP3 players, smartphones, and tablets allow us to listen to our favorite music almost everywhere. While driving in a car, we should also enjoy the highest sound quality. Learn how to use simulation to reproduce sound in one of the most difficult environments — a vehicle — to design better automotive sound systems.

Two professional chefs stand in a classroom, closely observing a soft-boiled egg. What may initially sound like a cooking class is actually part of a physics course offered at the Technische Universiteit Eindhoven (TU/e) in the Netherlands. Using COMSOL Multiphysics, students are investigating the science behind cooking the perfect soft-boiled egg. See how this innovative blend of simulation research and food science is teaching students how to build and test models.

When designing tall, slender truss towers topped with heavy loads, engineers may want to account for buckling. This requires calculating the critical compressive load of the structure at hand. Simulation is a time- and cost-efficient way to generate such results. Now, with simulation apps, this process is becoming even faster. Those without simulation expertise can easily run their own tests to calculate the critical compressive load for different truss tower configurations.

Pressure vessels are designed to confine liquids or gases. These containers are used in nuclear plants, throughout the chemical and petroleum industries, and even as water heaters in homes. In principle, the vessels’ internal pressure is much higher (or sometimes lower) than the ambient pressure, so the vessels must be carefully designed, as failure can result in severe damage. Today, we’ll show you how to use the Application Builder in COMSOL Multiphysics to create an efficient and accurate design workflow.

Today, guest blogger Linus Fagerberg of Lightness by Design, a COMSOL Certified Consultant, shares how multiphysics simulation provides accuracy in automotive muffler design. The acoustic design of mufflers in the automotive industry has traditionally been performed by an iterative process where different alternatives are compared by experimental methods until a satisfactory design is found. Numerical simulation can drastically reduce a project’s time and expenses, while simultaneously increasing the performance of the muffler.

Before building a house, architects and engineers look to optimize the sound quality of their design. Simulation tools like COMSOL Multiphysics are a valuable resource for doing so, generating accurate results while saving on costs. With apps, this workflow is becoming even more efficient. Those with little knowledge of simulation now have the ability to run their own acoustics analyses and obtain results more quickly. Take a look at our One-Family House Acoustics Analyzer for both insight and inspiration.

Whenever solid materials are heated enough, they will melt and then vaporize to a gas. Certain materials will even go directly from the solid to the gas phase, a process referred to as sublimation or ablation. If the material is heated strongly enough, there will be significant material removal. Today, we will look at how you can model this process in COMSOL Multiphysics.

Over the 10th through 18th centuries, the sound holes in violins evolved from a circular shape to an elongated f shape. In a recent research paper, MIT scientists and violin makers from the North Bennet Street School in Boston investigated the effects of this change in shape. They suggest that the f-shaped holes increase the air flow, making the bass notes of the violin twice as loud. Today, we will reproduce their findings with COMSOL Multiphysics.

Continuing his discussion of simulation apps, guest blogger Mehrzad Tabatabaian presents an app that he designed to study transient heat transfer in a nonprismatic fin. In earlier blog post, I spoke about my new book, COMSOL5 for Engineers, a resource designed to inspire and guide the creation of COMSOL models and simulation apps. Today, I’ll share a model with you that I created to analyze transient heat transfer in a fin as well as its corresponding app.

By design, façades are meant to be visually appealing. Aesthetics, however, aren’t the only concern. It is also important to consider elements such as stability, efficiency, and comfort. Engineers at Newtecnic use COMSOL Multiphysics to strike this balance, creating façades that are both eye‐catching and functional.

Pole vaulting is one of the most difficult events to master in track and field. Athletes must be able to run fast, be strong enough to elevate their body by holding the pole, and have excellent body control in order to change position while airborne. Analyzing the science behind this sport offers greater insight into the mechanisms that ensure success.
