In ANSYS AIM 18.2, several improvements have been introduced to the capabilities for simulating fluids. In this blog, I’ll highlight two of what I think are the most significant.
First: time-dependent fluid flow (including solid-fluid heat transfer). Time-dependent fluid flow enables the modelling of both applied physics conditions that change over time, and unsteady flow phenomena, for example varying inlet velocity and/or temperature in an internal pipe flow simulation; or vortex shedding from external flow around a cylinder, such as a chimney.
Second: particle injection (also known as discrete phase modelling, or DPM for short), where the injected particle could be a droplet, for example, a fire sprinkler system spraying water into air, or raindrops, but it could also be a bubble of gas into a fluid. Continue reading →
We continue to expand upon our best-in-class products and platform, and deliver on the Pervasive Engineering Simulation vision, with this week’s release of ANSYS 18.2. This latest release brings increased levels of accuracy, speed and ease-of-use — spurring more engineers to use simulation across every stage of the product lifecycle to design cutting-edge products more efficiently and economically.
More companies are turning to simulation to drive increasingly rapid and innovative product development and gain deeper insight into product design.
“Our customers rely on ANSYS engineering simulation technology to cut costs, limit late-stage design changes, and tame the toughest engineering challenges. This latest release continues to build upon the industry’s most accurate simulation portfolio, offering enhanced speed and accuracy – enabling more users, no matter their level of experience, to reduce development time and increase product quality.” said Mark Hindsbo, ANSYS vice president and general manager.
Wi-Fi access today seems more like a right than a privilege. But easy access to Wi-Fi is not widespread in many countries, especially in out-of-the-way rural areas where structural design and building of Wi-Fi towers can be challenging. In the interior of Brazil, only 22 percent of the people have Wi-Fi due to the costs of installing towers and the economics of providing service to sparsely populated areas. But startup Jet Towers is trying to remedy this situation using ANSYS AIM for structural simulation to design prefabricated, modular truss towers that can be installed and running within a week of purchase, instead of the normal five weeks for custom designed Wi-Fi towers.
The vast majority of engineering decisions are made without the insights that engineering simulation could provide into the impact of those decisions. It is estimated that 80 percent of the total product development costs are locked in by choices made early in the design process — and subsequent analysis and optimization now has to live within the implied constraints or face very costly and time-consuming design changes.
With increasingly complex products taking advantage of advanced materials, additive manufacturing and IoT, this issue will grow exponentially as many more permutations and design options must be evaluated for any given product. The only way to harness the potential of these mega trends, and tame the inherent complexity, is to bring simulation upfront in the product development process. To design the products of tomorrow, leading companies are doing exactly that.
Digital exploration has never been more vital to long-term business success than it is today. The product design space is exploding, driven by increasingly smarter devices, advanced materials, and next-generation manufacturing technologies like 3-D printing and mass customization. At the same time sustainability and cost put pressure on identifying and eliminating unnecessary safety margins, while still ensuring long-term product strength and durability. Design engineers have an unprecedented opportunity to innovate and explore product designs, but also orders of magnitude more complexity to manage. Continue reading →
A few days ago someone asked me if ANSYS flagship products are appropriate for the “average” engineer, and more particularly design engineers doing upfront simulation. I believe the better question to ask is which ANSYS products are geared toward design engineers, and why.
More often than not, design engineers are quite familiar with 3-D modeling tools, which are the starting point of simulations in the product development process. But given their focus on product design, manufacturability, documentation, etc., they typically do not have time or prior experience required to learn how to use a fully featured simulation tool like ANSYS Mechanical or CFD.

In a high school classroom, we battle constantly against a storm of changing technologies, competing educational needs, time and materials. As technology advances and industries change, educators do their best to keep students competitive and prepared for these changes. It becomes increasingly difficult, though, to develop meaningful challenges for students because of the cost of materials and other resources.
At the same time, it is challenging to justify the time and importance of your content against other subjects in the school, such as math or science. With the power of ANSYS AIM and ANSYS SpaceClaim, the technology education classroom has been given an important tool to fight back against the storm. Continue reading →
In ANSYS AIM 18, design engineers have reason to be excited about increased functionality for fluids, structural, thermal and electromagnetics. While the foundational problem-solving functionality has existed since AIM 16, new functionality is being added in every release so AIM can better address niche applications. One such enhancement I’d like to bring to your attention is solution-dependent expressions for applications like fan cooling simulation. While this isn’t something I guarantee you’ll use in your everyday simulations, it is a powerful feature needed for certain calculations. Continue reading →
It is hard to believe that a year has passed and it’s time to update you on what’s new for ANSYS 18 fluid dynamics. There is so much to write about and so little space in this blog!
I’m tempted to detail our breakthrough Harmonic Analysis method that produces accurate turbomachinery simulations up to 100X faster. Or I could focus on progress with Overset Mesh that speeds and simplifies simulations with moving parts. But that is not news, that just expected. ANSYS has been delivering new levels of accuracy and advanced modeling capabilities from the beginning. Instead, I’m going to shine the spotlight on an area you might not expect from ANSYS: Ease of use. Continue reading →
I’m excited and honored to share with you the innovations in the latest release of our suite of simulation solutions, ANSYS 18, on behalf of over a thousand R&D professionals at ANSYS. The driving force for these innovations is the spread of simulation to all areas of engineering practice, a trend we call “pervasive engineering simulation.”
This trend is enabling engineers to explore the design parameter space earlier in the product lifecycle (digital exploration), test thousands of detailed designs rapidly and efficiently (digital prototyping), and monitor and optimize their product’s operation after it has been deployed (using digital twins).
To make pervasive engineering simulation as easy as possible for all engineers, we’ve added a lot of new features to each product family, as you can see below. For more information on ANSYS 18, including demo videos, webcasts, application briefs and technical papers, see our ANSYS 18 web pages. Continue reading →
