Get an Inside Look at an Innovative Rainwater Drainage System
A multidisciplinary team worked together to design and install an aboveground rainwater drainage system in Copenhagen, Denmark. The resulting structure provides an ingenious system for dispersing rainwater runoff from nearby rooftops and mitigating noise pollution. Watch the video
Designing the Gold Standard of Immersive Audio for Virtual Reality Gaming
Tectonic Audio Labs created a state-of-the-art balanced mode radiator speaker using electromagnetics, mechanical, and acoustics simulation. The speaker was implemented into a virtual reality (VR) headset for Valve Corporation and is now regarded as the gold standard for VR audio. Read more
Bridging the Terahertz Gap with Simulation Software
Rather than coining the phrase “x-ray vision,” perhaps comic book writers should have called it “terahertz vision” instead. The precise blend of electromagnetic and material properties in the terahertz spectrum enables efficient applications such as simultaneous noncontact package inspection with spectroscopic characterization — to determine, for example, whether a package contains baking flour or an illegal or otherwise dangerous substance….
Designing Tidal Turbines That Are Safe for Marine Life
Creating clean energy alternatives for energy sources that generate greenhouse gas is crucial if we are to avoid excessive global heating and the rising climate crisis. A viable, renewable energy source are ocean tides, which, unlike solar and wind resources, are not weather dependent, making them predictable. Tidal energy can be harnessed by deploying tidal turbines into tidal streams. This…
Extracting Electrical Circuits from Electromagnetics
Simulations One of the common objectives of electromagnetics simulation is to extract lumped quantities that can be used in electric circuit simulations. Keep reading to get step-by-step instructions on how to perform such a task using the COMSOL Multiphysics® software… Read more
Modeling Graphene in High-Frequency Electromagnetics
Graphene and other 2D materials are the focus of intense research and application interests due to their promising properties. In this blog post, we are going to use the example of a graphene-based THz metamaterial perfect absorber to demonstrate how to model 2D materials accurately and efficiently in high-frequency electromagnetics. The discussed techniques are equally applicable to modeling other thin…
Analyzing Thermal Distribution in a Li-Ion Battery Pack
Lithium-ion (Li-ion) batteries are used to power a variety of devices, from toys and drones to cellphones and laptops to medical equipment and electric cars. To efficiently power such devices, the temperature distribution inside operating Li-ion batteries needs to be controlled, as deviation from optimal operating temperatures can cause a loss, or failure, in their performance. One way to analyze…
Making a Recipe for the Perfect Soft-Boiled Egg with Simulation
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. Read more
COMSOL Completes the Working Environment for Modeling and Simulation Projects with the Model Manager Server
The power of multiphysics simulation reaches all elements of product and process design projects with the introduction of the Model Manager server, which facilitates the collaboration between stakeholders and colleagues working on a modeling and simulation project. Read
Microlithography Lens
Microlithography lenses are used to project the image of an integrated circuit onto a silicon substrate. This tutorial demonstrates how to create a 21-element fused silica lens which has a NA of 0.56 which is designed to be used at a wavelength of 248nm. The lens, which has a total length of 1 meter, has a magnification of -0.25…
