Keynote Video: Designing Lightning Protection Systems with Simulation

Jenn Nguyen December 12, 2018

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.

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.

During routine exams, eye care professionals look for common refractive errors like nearsightedness, farsightedness, and astigmatism. As patients age, doctors also look for presbyopia, a loss of the accommodative amplitude that results long-term in a complete loss of the near vision. The visual accommodation process is complex, and useful eye properties needed to improve diagnosis and presbyopia treatment are difficult to obtain. To address the problem of measuring the refractive index of the lens, researchers developed a reverse engineering technique […]

Imagine that you’re indoors during a thunderstorm, watching raindrops trickle down the window. Despite the storm, you remain dry and warm thanks to the building envelope protecting you from the outside environment. To design a well-functioning building envelope, engineers need to account for a variety of different factors. Simulation can help address this need.

Guest blogger Bojan Jokanović of SGL Carbon GmbH, one of the world’s leading manufacturers of carbon-based products, discusses the optimization of thermal processes in the carbon industry. Carbon products are used in many industries, including semiconductors, car manufacturing, ceramics, and metallurgy. Properties of graphite including high-temperature stability, good thermal and electric conducting behavior, and high chemical stability make this material unique. However, carbon manufacturing is an energy-intensive industry. We must build digital process chains to optimize processes and minimize costs.

The average human heart beats around 100,000 times in a single day. With each beat, the four valves within the heart open and close, transporting blood unidirectionally through its chambers. By simulating heart valves, medical researchers can study their behavior to address various cardiac health issues. As an example, a team from Veryst Engineering modeled a heart valve opening and closing with the COMSOL Multiphysics® software.

Guest blogger Mandar Gadgil of Noumenon Multiphysics discusses modeling phase change in a thermosiphon. Thermosiphons have been used for keeping houses warm since the 1800s. These devices use central heaters and pipe networks that carry water and steam to different rooms. The cool part (figuratively) is that no pump is needed for fluid transport — convective currents induced by the heater located at the bottom of an installation are enough. Let’s discuss modeling thermosiphons using a “pseudofluid” with temperature-dependent properties.

Guest René Christensen February 28, 2018

Today, guest blogger René Christensen of GN Hearing discusses including thermoviscous losses in the topology optimization of microacoustic devices. Topology optimization helps engineers design applications in an optimized manner with respect to certain a priori objectives. Mainly used in structural mechanics, topology optimization is also used for thermal, electromagnetics, and acoustics applications. One physics that was missing from this list until last year is microacoustics. This blog post describes a new method for including thermoviscous losses for microacoustics topology optimization.

Guest Björn Fallqvist January 11, 2018

Today, guest blogger Björn Fallqvist of Lightness by Design, a COMSOL Certified Consultant, discusses using simulation to provide insight into the mechanical behavior of cells. Biological cells are essential for life as we know it. They not only store and replicate hereditary information in the form of DNA but also are instrumental in biological processes. In most, if not all, of these processes, the mechanical behavior of cells is a main factor in ensuring normal physiological functions.
