Another release of ANSYS fluid dynamics products, another round of great new capabilities. While some may say that a picture is worth a thousand words, I invite you to view the video below for more than 16,000 words on 16 Cool New Features of ANSYS Fluid Dynamics 16.0. And they are all winners — so this is not a ranking, just a list! Continue reading
With the release of ANSYS 16.0 last week, we know that you may be looking for more detail around “What’s New”. Our team of experts have put together a series of webinars over the coming weeks that will take a deeper dive into the enhancements you’ll see.
Register today for the webinar(s) that spark your interest. Continue reading
The peristaltic pump has become popular across various applications since being patented in the U.S. more than 120 years ago, and technological advances continue to make it relevant. The pump alternates compression and relaxation in its hoses and tubes, drawing fluid in and out. Our throat and intestines are actually good examples of peristaltic pumps.
I recently studied peristaltic pumps with computer analysis to see if I could improve the design through simulation. Where was the starting point? As a multiphysics program, ANSYS’ software suite provided a complete solution to the simulation of a peristaltic pump and I used software ranging from ANSYS Mechanical and ANSYS Fluent to ANSYS Explicit Dynamics Each tool has its unique capabilities and solved the problem at hand from different perspectives.

In 2013, over 4400 million tonnes of crude oil was extracted, which caters to roughly 33% of the global need for energy. Most of this oil is extracted from offshore sites and transported to shores for further processing. During this production and transport, if an accidental release of the crude or processed oil occurs, it is called Oil Spill. With the advancement of technology, volumes of oil spilled have reduced over last few decades, however, factors of human error and natural calamity can never be completely ruled out. Continue reading
Piezoelectric devices surround us in our everyday life. Our cars and trucks contain many piezoelectric devices, including fuel level sensors, air bag deployment sensors, parking sensors and piezoelectric generators in the wheels to power the tire pressure monitoring system. Your smartphones or tablet contains piezoelectric sensors that detect the motion and orientation of the device, which my kids were using to good effect to play “Need For Speed” yesterday. Many of us have ink jet printers at home, which can use piezoelectric printer heads to eject thousands of drops per second. Continue reading
I enjoy working on every article I coordinate for ANSYS Advantage magazine. I always learn something new while assisting ANSYS customers and staff tell their stories of excellence in engineering simulation. I have no favorites as I appreciate all of the articles. But, I decided to let our readers choose their top five, based on the power of downloading. The following are the most-read articles from the four issues (three regular issues and one special issue for oil and gas) of ANSYS Advantage published last year. All these stories have one thing in common: They feature robust and reliable design practices. Drumroll please …
A cool title, isn’t it? Hello ANSYS blog readers! This is my first time in this blog as a guest blogger. You will notice a brief resume of mine together my photo as the author of this post, but let me introduce myself so that you can understand why I am here writing about mesh morphing to the ANSYS audience.
I am a Professor at University of Rome, with good experience in fluid structure interaction (FSI) and Fluent customization using UDF programming. Five years ago, driven by a Formula 1 Top Team, I developed a powerful mesh morphing tool crafted by tough specifications. Managing any kind of mesh, precise, fast and parallel! Nothing at that time was able to do this kind of job. We tried to go with (RBFs) Radial Basis Functions mesh morphing, one of the most promising techniques. And we made it. Continue reading
The art of engineering can often be in finding pragmatic ways to use technology to solve real problems. While simulations may include an ever-increasing amount of geometric detail, it is not enough to simply generate ever finer meshes and use ever smaller time resolution. Simulations must still be solved in a reasonable time (and perhaps the one constant here has been that reasonable almost always means ‘overnight’). Therefore, until there is a dramatic breakthrough in computing power, modeling fluid flow will require engineering pragmatism in problem-solving for many years to come. But that need not be shouldered by the CFD engineer alone — ANSYS simulation software can support them in their efforts. ANSYS 15.0 contains multiple examples of how pragmatic approaches to efficient and effective simulation are contained in the software itself.
One such example is the dynamic combustion mechanism reduction capability in ANSYS Fluent. By automatically reducing the mechanisms to only the most important, dramatic reductions in simulation time can be achieved without the CFD engineer having to spend time and effort determining how to represent complex reaction mechanism in a simplified manner that models the behaviour sufficiently well. Instead, this pragmatism is built into the ANSYS software! Combined with further enhancements in ANSYS 15.0, it makes combustion simulation with even the most involved chemical reactions viable.
