The Future of Simulation via HPC

The What-If studies that our software performs go a long way toward influencing future product development. With tons of features and their resulting design complexity, short development cycles, and consumer/regulatory demand for safety, innovative products call for computing tools — and most people think of CAD and CAE. The silent partner in this mix is the hardware and its ability to quickly and accurately perform the calculations.

Over the past few decades, engineering simulation providers have satisfied demanding design requirements by expanding and deepening their multiphysics capabilities. Now we can imagine what if … and we can conduct studies to test what if … But the truth is that any given simulation tool paired with the best hardware platform is no longer a recipe to fast, reliable solutions. The simulation tool itself must be designed to reap the hardware’s full potential, such as highly scalable and distributed HPC environments. Continue reading

Aarushee Nair Visits ANSYS Pune, India Office

Our readers may recall that in June I wrote a post about an amazing young girl named Aarushee Nair. She is an eighth grade student of Sardar Patel Vidyalaya, New Delhi who is known for reinventing the liquid ORS pack and has recently applied for a patent. She has also been nominated for the 2013 Council of Scientific and Industrial Research (CSIR) innovation award for School Children. She is also an avid animal lover; enjoys basketball, swimming and photography.

We were so impressed with her work that we invited her to visit our ANSYS Pune, India campus and spend an educational day with our experts. Here is her story of that day. I hope you enjoy it. Continue reading

Unconventional Computer Simulations

I am always amazed when I learn about an unconventional application of computer simulation. A small news article appeared in the Times Of India — May 24, 2013 edition — that deserves a special mention here. It was about 13-year old Aarushi, an eighth grader from Delhi (India), who came up with a concept that can save millions of underprivileged children suffering from diarrhea.

The idea came as a solution to an awful report that she happened to read. It stated that every year millions of children under the age of five succumb to diarrhea. Young Aarushi first wanted  to invent a medicine to eradicate the condition, but after consulting her school teachers and the family pediatrician, the medicine idea seemed too big. This compelled her to perceive the solution from an entirely different angle. Continue reading

Bleeding-Edge Technology

The engineering simulation community is getting used to the role of ANSYS products behind bleeding-edge technologies, be it serving the exorbitant performance demands of F1 racing cars or extreme precise modeling of the nonlinear elasticity curve of dipole coils or designing entrance window for LHC Beam Dump Line at CERN. But I don’t usually drive a F1 car to the office nor does the existence of Higgs Boson affect my morning breakfast taste, despite being the building block of everything. As one of many tech-hungry people working, or rather living, on the edge and always anticipating what is next, I started thinking about where it all started and where are we now?

Have you ever thought the technology that was born more than 40 years ago, out of Astro Nuclear Research Labs, that has now penetrated into our routine life at such levels that we usually fail to think twice about it? The use of engineering simulation in the design or development of home appliances, cell phones, toys, etc. is well known. So let me draw your attention to a few very routine examples where we usually do not think that simulation matters. Continue reading

Simulation Technology at the Molecular Level

In recent years, I’ve come across a number of cases in which engineering simulation has been used in medical treatment for real people, all in various ways. It is no longer confined to research laboratories for demonstration purposes. Roughly speaking, these scenarios correlate the functionality of a living organ to a corresponding machine, such as a heart to a pump, bones to beams, and so on. Thanks to advancements in simulation technology, millions of people today have been cured in a way that is much better than once thought possible.

Now I am perplexed by this thought: How far could this analogy go? I got one answer while reading a featured story about employing simulation for cancer research on the Texas Advanced Computing Center (TACC) site, written by Dr. Suse Broyde, a biology professor at NYU. Continue reading
