The objective of simulation software is to inform design choices and provide validation results that include systems-level qualities, properties, characteristics, functions, behavior and performance insight. The simulation solution needs to go beyond the parts, or engineering disciplines of the design, and accurately describe the interacting effects of these parts as well as an accurate view into the detail of how these parts perform — essentially a virtual system.

Engineering teams and IT managers have been at constant odds with each other over vendor consolidation. IT wants to reduce costs by consolidating applications, Engineering wants best-in-class tools for specific tasks at hand. Over the past fifteen years, Engineering has had their way, and the IT organization has been left with a web of suppliers and tools to manage. Continue reading
You can’t turn on the news without hearing about the latest scandal to hit the sports industry. The New England Patriots — the National Football League (NFL) team that faces the defending champ Seattle Seahawks in Super Bowl XLIX this Sunday — are under pressure (pun intended) for using under-inflated footballs when they routed the Indianapolis Colts in the recent AFC championship that decided who would go on to the Super Bowl. One of the theories around DeflateGate is that a softer, less inflated ball will deform more when grasped, making it easier to hold. This could make for a more consistent pass, or a softer catch.
So, as simulation experts, what can we add to the national dialogue? Good question! Continue reading
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
System Simulation. It is an activity that can be defined broadly, and for many organizations it represents an aspiration for a type of engineering analysis that spans departments and disciplines and doesn’t fall into the familiar buckets of 3-D structures, fluids and electromagnetics. In contrast to 3-D multiphysics simulation, which seeks to understand coupling effects of different physical phenomena in the detailed design of individual components, multi-domain system simulation is used to analyze the interactions of many components operating together as a system, including software components describing embedded control and user interfaces.

Drones have been in the news a lot recently. The near miss between a commercial flight and an unidentified drone in Florida has been broadcast around the world and has opened lots of questions about how the issue of drones in civilian airspace will be handled as the number of drones increases exponentially. This has spawned discussion regarding the safety of aircraft in the event of a collision with a drone. What is for certain is that the FAA have got their work cut out to ensure the safe management of the exponential growth of the drone phenomenon. Continue reading
Nearly every industry today deals with issues of an increasingly complex supply chain, representing interconnected relationships between OEMs, and their Tier 1, 2 and 3 suppliers. Customers who perform simulation driven product development are acutely aware of the supply chain issues, because simulation tools used by various companies are usually different and often not interoperable. This is where standards come in — modeling standards like the IEEE VHDL-AMS language provide a clear modifiable description of behavior and all tools that support this language are expected to behave the same way. However, since each tool provides its own implementation of the language compiler (typically converting from the standard modeling language to C++ code), there can be some differences in behavior.

In today’s ultra-competitive environment, product differentiation increasingly depends on embedded software. From automobiles to airplanes to medical devices, systems architecture and embedded software are important parts of product development cycles. Being able to manage these processes effectively so that you get the desired results is becoming a differentiator.
Today, the cars that we drive have more that 10 million lines of code! Can you imagine the hours it takes to come up with the definitions of what the car should do and how it should do it — let alone implement all this correctly through software code? It’s a time-consuming process, and getting it right the first time is challenging. We’ve all seen examples of what happens when the code isn’t correct. Incorrect code can cost companies millions of dollars, and more importantly, it erodes customers’ trust in that brand.
By using model-based, production-proven software tools for the development of embedded code, products can be developed in a faster and safer manner. And, when coupled with a certified automatic code generator, compliance for standards like DO-178B/C in aerospace, ISO 26262 in automotive and EN 50128 in rail is more rapidly achieved.

Today is another very exciting day for ANSYS – we have completed our acquisition of Esterel Technologies, a leading provider of solutions that simulate the behavior of embedded software code. Our joint solution will enable customers to gain greater insight into the behavior of the embedded software as it interacts with the overall product – including electrical, mechanical and fluidic subsystems. This combination will accelerate development and delivery of innovative products — smart products — to the marketplace.
How do smart products get smart? Some of it comes from the design; a lot of it comes from intelligence that’s functionally built in — largely captured in the software that helps control and work with the microprocessors and all the electronics inside it. Continue reading
