Study Sensor Performance in Rapid Thermal Annealing with Simulation

Bridget Cunningham December 16, 2016

In rapid thermal annealing, a process step in producing semiconductors, measuring the temperature of a wafer is key. Without accurate measurements, overheating and nonuniform temperature distributions may occur, both of which impact the effectiveness of the process. This is why tools like the COMSOL Multiphysics® software give you the ability to analyze temperature distributions within an RTA design. From these results, you can better assess the performance of the sensor component and optimize its configuration to achieve accurate measurements.

For patients with renal failure, an efficient dialysis treatment is vital. One point of focus is designing high-performance dialysis equipment that increases contaminant removal, improving treatments like hemodialysis. To accomplish this, you can study aspects of the hemodialysis process, such as membrane dialysis devices, with numerical modeling apps. These apps, like the one discussed here, enable users to more quickly analyze the effects of different inputs and improve designs.

Learning how to use computational tools requires training. This is why a large group of stakeholders — one that continues to grow — relies on a small pool of experts to perform simulation analyses. The Application Builder, part of the COMSOL Multiphysics® software, is helping to bridge this gap. Simulation experts can now wrap models in an easy-to-use interface, making multiphysics simulation more accessible to a wider audience. See what our customers have to say about the Application Builder.

When performing a noise, vibration, and harshness (NVH) analysis of a transmission system, the elasticity of the gear mesh plays a crucial role in obtaining useful results. To help you create an accurate gear simulation, new features and functionality in the COMSOL Multiphysics® software enable you to evaluate gear mesh stiffness. Today, we’ll explain why it’s important to account for gear mesh elasticity as well as how to compute and include gear mesh stiffness in your multibody dynamics model.

If you’ve read the COMSOL Blog before, you might know that we like to include animations in our blog posts to help illustrate concepts more clearly. Most of these animations are exported directly from the COMSOL Multiphysics® software, which means that you can export animations for your own simulations, too. At the bottom of this post, we link to a video to show you how to do that.

Traditional lithium-ion batteries use an electrolyte based on a flammable liquid solvent, which can cause them to catch fire if they overheat. In recent years, nonflammable solid electrolytes have been investigated as an alternative to improve battery design and safety. Optimizing this technology for industrial applications, however, requires a better understanding of the electrochemical processes inside the device. Simulation serves as a valuable tool for this purpose, helping to realize the use of solid-state lithium-ion batteries in the near future.

In finite element modeling, you may encounter formulations where a force does not monotonically increase with displacement. You can see this property in many material models that include degradation of the material. Such behavior is represented by a negative stiffness. In this blog post, we discuss some examples of negative stiffness, including the physical backgrounds and numerical implications. These ideas are not confined to mechanical analysis, even though the term stiffness originates in that field.

Finding a scientific explanation for why ice is slippery seems simple enough, but it has actually been a subject of debate and confusion for centuries. As part of the world begins to bundle up for a blustery winter, let’s explore the science behind how the slipperiness of ice enables us to ski, skate, and even fall down in the parking lot.

Transdermal drug delivery (TDD) patches continuously deliver drugs into the body for a certain amount of time. However, the skin is designed to keep out foreign substances, like drugs. To create a TDD patch that successfully bypasses this barrier, simulation can be used to study drug release and absorption into the skin. To analyze this process, Veryst Engineering created a TDD patch model with the COMSOL Multiphysics® software and compared the results to experimental data.
