2015 ANSYS Hall of Fame Winners

The world of multiphysics simulation is growing ever more ambitious each year. That is obvious from this year’s ANSYS Hall of Fame Competition, for which the company recently selected five top entries that typify the best of the best.

From a company developing new spinal instruments to reduce the risks of scoliotic surgery, to a university’s examination of how a leatherback turtle would weather climate change, this year’s top five represented contributions from multiple industries and amazing applications. Continue reading

Can You Simulate a Better Peristaltic Pump?

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.

Taking Material Modelling to the Next Level – Implementing a user-defined constitutive equation using USERMAT

From a structural reliability point of view, it is very important to understand and accurately characterize the material behavior when designing or analyzing an engineering application.

In this respect, ANSYS Mechanical software provides a vast library of material models that can help users simulate various kinds of behaviors such as elasticity, plasticity, creep and hyperelasticity, just to name a few.

Although these models can be used to investigate the mechanical response of a large number of different materials such as metals, rubbers, biological tissues and special alloys, users may wish to incorporate their own material laws into ANSYS. Continue reading

Update on Tablet Computing and ANSYS Mechanical

Some time ago, I wrote a couple of posts describing the performance of ANSYS Mechanical APDL on several different tablet computers. Previously, I had studied two separate tablets: one from Fujitsu, which was more of a shrunken laptop with an Intel® Core i5 processor and a second from Dell, which had an Intel® Atom™ processor and was more in line with the look and feel of an iPad. The Fujitsu tablet was clearly faster, but bulkier and pricier. The Dell tablet was lighter, smaller, cheaper, and also less powerful. Continue reading

ANSYS Webinars This Week – Nov 10

ANSYS Webinar Learning EventsThis week our ANSYS webinars line-up includes topics such as model-based systems engineering, product-related tutorials with ANSYS Mechanical and ANSYS Polyflow, as well as a very interesting look at how fluid simulation is used to better everyday life.

Our Improving Your Everyday Life webinar is a part of the Convergence Webinar Series. ANSYS customers, University of Parma and Bissell Homecare, Inc, give us insights into how they use simulation. Later in the week, researchers at Intevac and Ozen Engineering show how they simulated the fluid—structure interactions (FSI) of the human left ventricle with Hybertrophic Obstructive Cardiomyopathy (HOCM) to better understand the condition in the hope of saving lives.

Magnetoelasticity: A 20-Year Journey from Cornell to Michigan Tech to ANSYS INC.

I was reminded of Professor Francis Moon, Joseph C. Ford Professor of Engineering Emeritus, when I visited Cornell University this summer for the 2014 Engineering Development Forum. You see, 20 years earlier I had just completed my PhD dissertation in the area of magnetoelastic buckling, a topic that was initiated by Professor Moon in 1968. His breakthrough research created immense interest around magnetoelasticity in the research community. Continue reading

When Universities Fly High – University of Naples

20140226_135427 (1)We are pleased to present a guest blog from Giovanni Paolo Reina and Angelo Della Sala at the University of Naples.

The weapon-aircraft integration is one of the most important aspects in military aircraft design and for the study of its performances. In particular store separation problems, i.e. problems related to the release of underwing bodies during the flight, are very critical because they occur during a flight operating condition.
