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.

Wow, the 2014 Olympic Winter Games in Sochi have been amazing and make me even more impatient to go to skiing in early April. I’ll especially remember three of the sporting events. First, Bart Swings from Belgium finished in fourth place in the 5,000-meter speed skating just behind a fully Dutch podium. Maybe aerodynamic simulation could have improved his performance and delivered him a place on the platform. There was also some great ski jumping where the skiers literally flew, and I found a flapping ski to perfectly illustrate fluid–structure interaction. I don’t know if this flapping is good or bad for performance. What do you think? Finally, I’ll remember the breathtaking downhill race. Continue reading
When I look back over the last decade at the trends in CAE simulation, one thing that stands out is the increase in the general complexity of models being investigated. Today, with progresses in computing power and parallel computing, 3-D simulations are commonplace and geometries are less and less simplified. As a result, many CFD engineers choose to spend less time on geometry simplification and clean-up of corrupted geometries (for example gaps or holes) and solve larger models using the power of parallel simulations.
Prior to CFD analysis, we often have to extract the fluid volume of a given geometry. After all, we CFD engineers are often most interested in what is happening inside or outside the solid objects! Extracting the fluid volume from solid CAD entities using a Boolean tool at the geometry level is a great strategy for simpler geometries but can become extremely troublesome when the number of parts in an assembly increases and gaps or holes (geometry imperfections) exist. When you are looking at cases containing hundreds or thousands of parts, most engineer’s (including myself!) eyes start to glaze over at the very thought of preparing the geometry for analysis!
Our world-wide Convergence Conferences are back and better than ever. With even more locations in 2014, consisting of excellent presenters that use ANSYS software, you just may find a tip a two to solve a complicated problem that you’ve encountered.
The conference also offers you the opportunity to meet and network with ANSYS engineers and managers, hardware/software partners, simulation industry thought leaders and other ANSYS users to learn how to leverage our suite’s capabilities in solving complex product development challenges. Regional conferences begin in April and are hosted in over 25 countries throughout the year. Continue reading
ANSYS had an exciting week at DesignCon 2014 in Santa Clara, California a couple of weeks ago. After MANY hours of demos, networking, panel discussions, award dinners and paper presentations, we are back in action and ready to take what we learned about the latest industry trends and challenges and see how we can apply it to ANSYS simulation.
At the show, we announced a new suite of electronic products designed to help users quickly identify potential power and signal integrity problems throughout the PCB design flow. Attendees of our in booth presentations on the new SIwave were excited to see the new targeted capabilities and design flows to address such critical issues as DC voltage drop analysis, power integrity and automated decoupling capacitor optimization and end-to-end signal integrity analysis design flow.

Before I get to the ANSYS Webinars for the week, today in the United States we celebrate the birthday of George Washington, the first President of the United States. But, in his honor, I cannot tell a lie. Did you know that technically Mr. Washington was not the first President? Nope. That honor really goes to John Hanson. A fascinating story you might want to check out after you register for one of our free webinars this week.

A large part of the World celebrates Valentine’s Day today, and personally I have been reflecting on some of the things that I love. My husband and my sons top the list. Some of my hobbies are on there too. So is the work I do — product management for an engineering simulation software development company. Through my work, I have been fortunate to see the brilliant things engineers around the world do that make things better for their communities, their customers, people in general, and the world at large. It is the potential and opportunity that engineering offers that caused me to pursue it myself. I sometimes wonder why I don’t encounter more women working in engineering. That fact is so at odds with how I was so fortunate to do so, to almost fall into the field, without ever being discouraged or thinking maybe I could not. Continue reading
