Using ANSYS Super-element with GENESIS for Efficient Topology Optimization

Anil Kumar (Senior Engineer – ANSYS) and I thought it would be interesting to share information about integrating ANSYS super-element with the GENESIS structural optimization extension for ANSYS. With ever-increasing computational power, engineers can solve larger FE models in less time. However, optimization is still a serious concern because it is an iterative process and the FE analysis usually needs to be performed multiple times.

Typically, the parts that engineers choose to optimize are only a subset of large assemblies. For example, when optimizing the chassis, the engines and other components attached to it are not designed at the same time. It is not necessary to model all the details of those components not participating in the optimization.

New Version of ANSYS Mechanical – New Capabilities

Engineering is a pretty exciting place to be right now. There seems to be amazing news about new products and technologies being tested and released nearly every day. ANSYS 18.2 just launched and it’s packed with cool stuff. ANSYS Mechanical has a raft of new capabilities to help engineers make new technologies a reality. 

I’m amazed at some of the commercial space industry achievements going on right now and of course, being a big car fan, the technology going into the automotive sector is just incredible. In order to bring these products to market, big changes are taking place in the companies designing these products.

More efforts are being put into every aspect of product design and the drive to build better products faster means increased pressure on engineers. Continue reading

ANSYS 18.2 Enhances Simulation Speed and Accuracy

ansys 18 2We 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.

Highlights of the release include: Continue reading

The Engineering Behind Why It’s Too Hot to Fly

I’ve read a lot of articles talking about an interesting fact: this summer was so hot that in some cities like Phoenix aircraft could not fly. If you are an engineer or a pilot, it should not be a surprise that in hot weather an aircraft’s performance can deteriorate until the point it is unsafe to attempt take off. But maybe you have not considered all the possible causes of why it’s too hot to fly. I will try to explain things in a very basic and simplified way, for the benefit of those who are not familiar with these phenomena.

In Search of a Better Design with Topology Optimization

When reducing the mass of your models, are you also optimizing for other important design elements such as thermal performance, fabrication constraints or if the casting needs to be water-tight?

Thermal problems are very common in engineering design such as automotive powertrain, electronic cooling system, etc. Topology optimization can also be applied for thermal analysis to improve the cooling performance or for coupled thermal-mechanical analysis to improve the thermal and structural performance simultaneously.

Additive Manufacturing – Re-engineering Engineering

On the 11th of June I, along with quite a few of my colleagues and a number of our customers will be heading to Sweden to the NAFEMS conference. I’ll be there to talk about our work in the area of Additive Manufacturing.

Additive manufacturing is the poster child of the engineering world right now. There are other posts on the web and on the ANSYS blog talking about this and what the opportunities are that it brings. But I wanted to talk about the changes that must make to the whole product development process.

It’s pretty well understood that product development is pretty well down the path to shift away from a time when simulation was used to figure out why something broke. Now simulation is more routinely being used up front in the design process to develop products that are, more often, right first time. Continue reading

Learn About the Many Innovative Features of ANSYS 18

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
