How to Create Custom Reports Using Report Templates

Magnus Ringh December 24, 2018

Reports are valuable for documenting and showcasing results from your simulations. As of version 5.4, the COMSOL Multiphysics® software includes support for report templates, which you can use to create custom reports. In this blog post, we describe how to add report templates and show some examples of how they can be useful for creating reports with specific layouts and contents.

Piezoelectric devices are widely used as sources to generate sound waves or receivers to detect acoustic signals. In applications such as ultrasound imaging and nondestructive testing, the same transducer can be used as a transmitter to send a source signal and receiver to detect echoes. Modeling these devices often requires transient analyses with time of flight as output. Let’s discuss how to use the COMSOL Multiphysics® software to model a piezoelectric device as both a transmitter and receiver.

When it comes to synchrotron light sources, brighter is better. By using bright beams in their accelerator, researchers at the Advanced Photon Source (APS) synchrotron facility can efficiently gather detailed data. In collaboration with APS engineers, Nicholas Goldring of RadiaSoft LLC creates and distributes simulation applications for designing vacuum chambers relevant to the APS. Below, find a video recording and summary of his keynote talk from the COMSOL Conference 2018 Boston.

Traps are omnipresent in practical semiconductor devices. When modeling these devices, the Trap-Assisted Surface Recombination boundary condition adds the effects of charging and carrier capturing/releasing by surface or interface traps. Here, we examine a tutorial model of a metal-oxide-silicon capacitor (MOSCAP) to demonstrate how to use the feature in the Semiconductor Module, an add-on product to the COMSOL Multiphysics® software.

Émilie du Châtelet was a French physicist, natural philosopher, and mathematician who contributed to our understanding of Newtonian mechanics. Her translation of Sir Isaac Newton’s book the Principia is considered the standard version in French today. In addition to translating this work, she included her own commentary, adding a conservation law for total energy that emphasizes the role of kinetic energy. She is also famous for her masterful textbook, Foundations of Physics, which takes a philosophical approach to the sciences.

Groundwater is an important source of irrigation and drinking water, so keeping it pure is crucial. However, once contaminants get in, it isn’t so easy to get them out — creating systems to remove contaminants from groundwater requires an understanding of the complex way immiscible fluids move through soil. To gain insight into this behavior, engineers can use the phase transport functionality in the COMSOL® software.

Lightning risk is an important consideration in various industries, including aircraft and wind turbines. But how do you study the behavior of a phenomenon that can cause extreme damage in microseconds? And how do you make sure your product can withstand a lightning strike? In his keynote talk at the COMSOL Conference 2018 Boston, Justin McKennon of NTS Lightning Technologies answers these questions, discussing how multiphysics simulation helps in the design and certification of lightning protection systems.

The COMSOL Desktop® is the integrated user environment for creating and managing simulations in the COMSOL Multiphysics® software. It includes the Model Builder window, model tree, Graphics window, as well as menus and toolbars with a multitude of modeling tools. In this blog post, we will show you how to customize the user interface and use a variety of keyboard shortcuts to get the most out of the modeling process.

Until the early 1900s, shock waves were an academic problem studied from a theoretical point of view only. Many great scientists, including Lord Rayleigh, worked on the field until the theory of inviscid shock waves was established in the 1920s. During World War II, this theory started to be applied, mostly to supersonic vehicles. To study shock waves, one important gas dynamic instrument is the shock tube, which is used to test supersonic and hypersonic flows and high-temperature gases.

Composite materials are heterogeneous materials composed of at least two integrated components. Among the different types of composite materials, layered composite materials are quite common and are widely used for aircraft, spacecraft, wind turbine, automobile, marine, buildings, and safety equipment use cases. The Composite Materials Module, add-on to the COMSOL Multiphysics® software, includes built-in features and functionality specifically designed for studying layered composite structures. Fiber-reinforced plastics, laminated plates, and sandwich panels are a few common examples of layered composite materials.

Heart failure is a global health concern, affecting millions of people and keeping them from their everyday lives. But what if there was a device that could keep patients’ hearts pumping and even improve their quality of life? In his keynote presentation at the COMSOL Conference 2018 Boston, Freddy Hansen from Abbott Laboratories discussed a heart pump that could do just that. If you missed his talk, you can watch a recording of the video and read a summary below.
