Brush those pearly whites! 🦷 🪥

We're having some fun with simulation for Dental Hygiene Month, for example by simulating the abrasive contact between tooth and brush through flexible fiber Discrete Element Method (DEM).

⚡Modeling Turbofan Engines to
Understand Aircraft Noise⚡

This simulation shows the complex flow of air particles
through the Source Diagnostic Test turbofan engine. By simulating the fan’s
rotations, researchers can target design innovations and modifications to reduce the impact of fan noise on people living and working in areas with heavy
air traffic.

🔊 A New Dimension in
Audio Performance: Siemens Simcenter STAR-CCM+ Acoustics!

The Lighthill Wave Model analyzes the propagation of sound
using the acoustic analogy method, but neglects the effect of the flow field on
sound propagation. It can be used in applications such as heating, ventilation,
and air conditioning (HVAC) duct noise.
Simcenter STAR CCM+ Acoustics is designed to optimally
analyses and optimize the sound propagation of the flow area. You can take the
lead in aero acoustic simulations and perfect your product sound performance!

“Aerodynamically, the bumblebee shouldn’t be able to fly, but the bumblebee doesn’t know it, so it goes on flying anyway.” – Mary Kay Ash This scientific paradox is one of the most well-known misconceptions of aerodynamics in the realm of animal life and has even gone on to become a popular phrase of encouragement, urging people to follow their dreams despite what others might say. The misconception was coined by zoologist Antoine Magnan and his assistant André Sainte-Lague, when they attempted to calculate the lift provided by a bumblebee’s wings in 1934. The problem in their methodology was that they assumed that the small insect’s wings functioned as an aeroplane’s wings would, and their calculations resulted in the conclusion that it is impossible for bumblebees to fly, even though they do it all the time. The fact is that bumblebee’s wings do not function like those of aeroplanes. While the human invention is almost always horizontal (deviating from the plane of motion by less than 5°), the wings of a bumblebee are in a constantly changing angle of attack, often times greater than 50°. At high angles of attack, the leading edge of a wing will create a small vortex – or a sideways swirl of air – that provides a burst of lifting force. In a stationary wing, the vortex would at first provide the lift force, but it would then cancel itself out as the turbulent flow of air passed the wing, making it lose its lifting force in what is called a stall. Bumblebees avoid the stalling problem thanks to two factors: the variable angle of attack of their wings, and the frequency of their wing strokes. The angle at which bumblebee’s wings move through the air is often over 50° off from the path they follow, and on the backstroke, the bee’s wings will flip over. This motion not only provides extra lift by generating a new, inverted leading edge vortex, but also provides rotational lift, an effect similar to the one we can appreciate on a spinning football. To top it all off, bumblebees flap their wings at over 200 times a second, and so their wings can take advantage of the new vortex before the first one has the chance to cancel
itself out.

helps us achieve more flexible and customizable solutions by increasing the diversity of engineering projects with the freedom to combine different cell types in a single model in the cut mesh and rotating impeller area where the flow is aligned. Motion modeling is of vital importance in order to create the correct depression and trim in resistance calculations. This helps us achieve more accurate results in the design process, resulting in excellent performance and reliability. With these comprehensive features offered by Star CCM+ software, you can perform our engineering projects faster, more efficiently and
more reliably.

🚀 Iterate at the Speed of
Thought

💡
Imagine a development cycle paced by engineering ingenuity, not CPU clock time.
Where ideas can be tested without constraints of HPC and budget limitations,
where unconventional ideas are an asset rather than a liability, as they can be
assessed quickly and efficiently.
That is the promise of AI-accelerated engineering.
🔍
See the example below. Each result from first-principle CFD computations takes
hours. However, AI predictions for those unseen geometries can be achieved in
just the refresh rate of this video: 70ms.
