How to Avoid Sacrificing Accuracy for Speed When Prepping and Meshing CFD Geometry

I don’t know about you but I want the best I can get — whether I’m doing CFD prep and meshing or just living my life. It had better be good and speedy and easy — I want it all! Unfortunately, life doesn’t work always that way.

FenceFor example, I have a beautiful wrought iron fence in front of my house. The problem is that the fence is made of steel and as we all know, steel has the unfortunate property of rusting as the paint ages and loses integrity. So, this summer I have a big project to scrape, brush and repaint the metal. I’m not looking forward to the many hours of hands on time that will take! Continue reading

Zyz Sailing Team Designs Using ANSYS

Zys sailing teamZyz sailing team started designing and manufacturing small sailing boats in 2008 to participate to Italian inter-university regattas called 1001velaCUP. During the first eight-year experience of the team, different boats have been launched, trying to optimize all different aspects that influence the final performance of a boat. R3 class rule adopted in this competition imposes geometrical and structural constrains to the design process: maximum length x beam of the boat is 4,60 x 2,10 m, while a minimum percentage weight for the hull constituted by 70% of plant-origin material is imposed.

Why 10x More HPC Matters?

hpc scalibilityIn my talks with engineering managers, flow analysts and IT staff, I often hear variants of this question. Why is more computing power a strategic asset for my engineering department? Why does scalability matter for my simulation jobs that don’t go beyond 32–64 cores in parallel? What’s in it for IT when we are stuck with our current HPC server or cluster for at least two years? Let me try to answer each of these questions.

10 Compelling Reasons to Upgrade to ANSYS 17 for Healthcare Applications

On January 27, ANSYS released its biggest version ever, ANSYS 17.0. Although the ANSYS simulation platform is renowned for its comprehensive coverage of virtually every industry through its extensive range of simulation tools, this latest release is particularly suited for the healthcare industry, whether you are modeling structural, fluid or electromagnetic applications — not to mention those of you engaged with multiphysics modeling. Among the hundreds of new features coming with this release, it might be easy to miss those which are truly important for the medical device, pharmaceutical or clinical sectors.  Let me highlight 3 new or enhanced capabilities.

BadgerLoop Takes Number 3 Spot at Hyperloop Competition

badgerloop hyperloop competition ansysOur story began in the afternoon of Monday, June 15, 2015. It was just like any other day until an email with SpaceX’s announcement of a Hyperloop competition was received. We got to thinking and within a week, BadgerLoop was created purely by word of mouth. 15 students worked from around the world, while on summer internships, to solidify the core of BadgerLoop.

Better, Faster CFD in ANSYS 17.0

Fidelity and accuracy is critical in CFD simulation.  After all, physical prototyping and testing can only be reduced and even replaced by CFD if one can expect accurate results. Up to now, high fidelity, high accuracy results came with a price. Complex geometries — the realistic, no holds barred type — required hours of manual effort to clean up the model and then prepare the mesh. Users were tempted to cut corners and take short cuts that sped up prep but took a toll on accuracy and fidelity. Unfortunately, there is no way of knowing just how those inaccuracies skewed the results, putting any recommendations in doubt. For example, if you don’t resolve a boundary layer correctly then any aerodynamic drag figures could be highly inaccurate. Continue reading

Flint Water Crisis Explored: Keeping Our Water Supply Clean

Clean water is one of the most basic necessities of our lives. Our health depends on it. What transpired in the Flint water crisis in Michigan recently has shocked the nation. President Obama declared a state of emergency and there are demands that the Governor of Michigan steps down. It all started when, in order to reduce cost, the City of Flint officials decided to use Flint River water for residential consumption without adding orthophosphate, a chemical that coats the pipe interior thereby inhibiting any leaching of lead.

Introducing ANSYS 17.0 – 10X Productivity, Insights and Performance

17.0With a number of emerging technologies and trends on the horizon, it is an exciting but challenging time to be an engineer. The convergence of new technologies into Industry 4.0 is ushering in an era of unbound product innovation. With the advent of the Internet of Things, a tighter integration of the digital world and the world of machines will profoundly transform consumer and industrial markets. New advanced materials are enabling engineers to create substantially lighter and sustainable designs. New technologies are changing the way we harvest, store, and use energy. And the possibilities of virtual reality and additive manufacturing are freeing engineers to explore more radical designs, free of manufacturing constraints. Make no mistake, engineering simulation will be the key to unlocking the power and potential of this new industrial revolution, and to this end, I am excited and honored to announce the next release of our simulation platform on behalf of over a thousand R&D professionals at ANSYS.

HyperXite and the SpaceX Hyperloop Pod Design Contest

Editors Note: Today’s Guest Blog is brought to you by HyperXite’s Project Leads at the University of California, Irvine (UCI) who are competing in the SpaceX Hyperloop Pod Design Contest.

What if there was a system of transportation cheaper, faster and most importantly, safer than driving, flying or boating? This next evolution in transportation is the Hyperloop, to design and build a pod that can transport 840 people between Los Angeles and San Francisco at 760 mph while floating on a cushion of air. Developing this technology is, however, a huge endeavor and the SpaceX Hyperloop Pod Design Contest was created to ‘crowd source’ the design of the vessel. Continue reading
