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.

Today, guest blogger and Certified Consultant Nagi Elabbasi of Veryst Engineering shares simulation research designed to optimize band gaps for phononic crystals. Phononic crystals are rather unique materials that can be engineered with a particular band gap. As the demand for these materials continues to grow, so does the interest in simulating them, specifically to optimize their band gaps. COMSOL Multiphysics, as we’ll show you here, can be used to perform such studies.

Today, guest blogger Mehrzad Tabatabaian discusses turning COMSOL Multiphysics models into apps, a point of focus in his book COMSOL5 for Engineers. Accurately predicting the behavior of objects and systems is a key element in any design workflow. Computational tools like COMSOL Multiphysics help to ensure this, enabling simulation experts to easily test different designs. Now, with the Application Builder, these experts can turn their models into easy-to-use apps that can be accessed by a larger technical community.

Year by year, wearable technology grows in popularity for both consumer and medical applications. These devices are meant for continued use, but the heat that they produce could lead to malfunction and burns if not properly designed. To prevent injury to the device user, it’s important to take the effects of heat transfer into account during the design process. The simulation capabilities of COMSOL Multiphysics make this possible.

Previously on the blog, we detailed the standards employed to describe piezoelectric materials. There are two piezoelectric material standards supported in COMSOL Multiphysics: the IRE 1949 standard and the IEEE 1978 standard. Today, we will demonstrate how to set up the orientation of a crystal, specifically an AT cut quartz plate, within both standards.

Electrical cables are classified by parameters such as impedance and power attenuation. In this blog post, we consider a case for which analytic solutions exist: a coaxial cable. We will show you how to compute the cable parameters from a COMSOL Multiphysics simulation of the electromagnetic fields. Once we understand how this is done for a coaxial cable, we can then compute these parameters for an arbitrary type of transmission line or cable.

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.

Have you ever run a large parametric sweep overnight, only to discover the next morning that the parametric solver is still not finished? You may wish you could inspect the solutions for the parameters that are already computed while waiting for the last few parameters to converge. The remedy to this problem is to use a batch sweep, which automatically saves the parametric solutions that were already computed on a file that you can open for visualization and postprocessing purposes.

If you are looking for an interactive training event where you can learn the basics of COMSOL Multiphysics and the Application Builder in just one day, and at no cost — keep reading. COMSOL Days are training events held around the U.S. and globally. These events include minicourses and networking opportunities that will leave you ready to start using simulation and building apps with confidence.

The rotation of the impellers in a mixer or stirred reactor creates ripples on the liquid surface when the agitation is moderate. If the ripples are small in comparison to the height of the fluid in the vessel, the shape and height of the free surface can be explicitly calculated from the velocity field in a separate solution step. The latest version of the Mixer Module in COMSOL Multiphysics includes a Stationary Free Surface feature for such computationally inexpensive calculations.
