What do Tesla Motors, BMW, Honda, Toyota, Ferrari, Denso, Panasonic, SL Corporation, Cummins, Tenneco, and Honeywell, have in common? Well, not only are they leaders in the automotive renaissance, but they all delivered presentations on leading-edge simulation at the 2014 Automotive Simulation World Congress. Continue reading
This is the third year that ANSYS hosted the Automotive Simulation World Congress (ASWC), an international conference focused on engineering simulation in the ground transportation industry. The ASWC is an annual conference that rotates between the three major regions of the world. In previous blogs, I wrote about the 2012 and 2013 ASWC’s held in Detroit and Frankfurt respectively. This year the conference was held in Tokyo on October 9 and 10. Continue reading
The U.S. Environmental Protection Agency (EPA) recently released new Corporate Average Fuel Economy, or CAFE standards for light duty cars and trucks. These standards are designed to reduce greenhouse gas emissions and improve fuel economy, leading to model year 2025 vehicles that will emit just one-half the greenhouse gasses that model year 2010 vehicles do.
To reach these ambitious goals, the new CAFE standards mandate that automakers raise the average fuel efficiency of new cars and trucks to 54.5 miles per gallon by 2025. These are lofty and commendable goals. But for engine designers and automakers, are the new standards even feasible for real-world vehicles? The EPA believes they are, and has established a new program to prove it. Continue reading
Road accidents are one of the leading causes of unnatural deaths around the world. The World Health Organization’s Global status report on road safety in 2013 indicates that worldwide the total number of road traffic deaths remains unacceptably high at 1.24 million per year. This is a staggering number.
As the number of vehicles increase, resulting in a corresponding increase in accidents, auto safety is emerging as one of the most important aspect of automotive product design. Broadly, automotive safety can be classified into passive and active safety. While passive safety covers basic components of the vehicle (example: seat belts, air bags, vehicle structure etc.) in addition to driver behavior; active or predictive safety usually refers to the use of technology to avoid collisions or at least mitigate their effect (example: crash avoidance and driver assistance systems).

When we think of “mobile devices”, images of smartphones and tablets come to mind. These devices connect us virtually to events around the world, our family, our friends, and the global marketplace, without ever leaving our homes. And with the advancements in automotive electronics, our driving experiences can also be enhanced, where we are as globally connected to our environment as our smart phones. Such connectivity could augment our driving experience and enhance our security, by providing early warning and accident avoidance capabilities. Imagine cars being aware, not just of the surroundings but also aware of their driver. Imagine a future where your interface to the virtual word is limited not to queries on a touch screen, but rather the entire environment of your car, from the windshield to the seat to the car electronics, which are all engineered to provide a globally connected driving experience unique to you.

Today’s automotive community is increasingly called upon to think strategically and form unique relationships that expand its reach in a new era of cross-industry collaboration. We’re eager to share our excitement about Reaction Design’s new role at ANSYS (especially as it applies to developing optimal auto combustion processes) and reveal our shared vision for our more powerful and predictive simulation technologies.
We’re looking forward to telling you about it at the upcoming SAE 2014 World Congress and Exhibition, being held April 8 through 10 at Detroit’s Cobo Center. A must-attend for the automotive engineering community, this event represents an unparalleled opportunity to explore new technology through both technical sessions and the Innovators Only Exhibition.

On March 27 at 4 pm GMT, 12 pm EST, I will have the pleasure to participate in an exclusive, one-time, non-recorded webinar hosted by SAE international with Al Peasland (Head of Technical Partnerships, Infiniti Red Bull Racing) and Nathan Sykes (Team Leader for CFD and FEA, Infiniti Red Bull Racing).
Since the birth of the Infiniti Red Bull Racing (IRBR) Formula 1 team almost 10 years ago, simulation has played a vital role in assisting the team to develop its cars aerodynamics through its CFD software and services. I have been the technical account manager for the IRBR account for over 6 years. In addition to developing and solidifying our technology relationship, I have witnessed first hand the impressive integration of ANSYS software into a Formula 1 CFD process. I take great joy (and pride!) working tirelessly and collaboratively with IRBR to deliver technology that has proved superior in concept and execution, ultimately helping to design the cars that have delivered the quadruple championships, which have been awarded to the team over the last four consecutive years.

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!
