Developing a luxury electric vehicle (EV) from scratch with a short deadline demands organization and access to the right technology to get the job done. Lucid Motors of Menlo Park, California, met the first challenge by putting all the engineers in one room so the structural and aerodynamics engineers would know what the battery, motor and power electronics engineers were doing, right from the start. This collaborative environment has helped them to design a unique automobile with more passenger space by reshaping the battery stack, while optimizing the electric motor, the cooling system, the aerodynamics and the battery life.
With a clear mission in mind, huge government funding and thousands of talented scientists, the early pioneers of space exploration were disrupting innovators, able to achieve what many thought impossible. Then organizations grew in size, and projects and goals multiplied while public funding was often in doubt. Despite other significant success, this led to a slowdown in the innovation pace. Now, another wave of innovators has come: Space 2.0 players.
With no history, no legacy of tools and processes and no constraints in workflow design, they were able in a few years to attract huge private funds and challenge the leadership of the big established players.
Both the old players and the newcomers rely on simulation, but I see a big difference in the results they get in terms of efficiency, costs and innovation pace. The secret is in how they implement it. Continue reading
A few days ago someone asked me if ANSYS flagship products are appropriate for the “average” engineer, and more particularly design engineers doing upfront simulation. I believe the better question to ask is which ANSYS products are geared toward design engineers, and why.
More often than not, design engineers are quite familiar with 3-D modeling tools, which are the starting point of simulations in the product development process. But given their focus on product design, manufacturability, documentation, etc., they typically do not have time or prior experience required to learn how to use a fully featured simulation tool like ANSYS Mechanical or CFD.

When designing reliable, leading-edge products, companies must take many factors into account. In product engineering, one of the most common concerns is temperature which affects equipment efficiency and performance, and could lead to failure as well as health and safety issues. The latest issue of ANSYS Advantage magazine reveals how companies across a wide range of industries are using simulation to address thermal issues. Continue reading
ANSYS 16.0 delivers the first integrated and comprehensive multiphysics simulation environment designed for all engineers. This environment is called ANSYS AIM and it is the further realization of the ANSYS Workbench strategy to revolutionize engineering processes through Simulation Driven Product Development.

The world of multiphysics simulation is growing ever more ambitious each year. That is obvious from this year’s ANSYS Hall of Fame Competition, for which the company recently selected five top entries that typify the best of the best.
From a company developing new spinal instruments to reduce the risks of scoliotic surgery, to a university’s examination of how a leatherback turtle would weather climate change, this year’s top five represented contributions from multiple industries and amazing applications. Continue reading
We’ve actually got quite a full calendar of ANSYS webinars and events this week that should appeal to a wide audience. Whether you’re traveling to an in person event, an industry trade show, or you prefer an online experience, there’s a little bit of everything this week..
You can view a full calendar below, but let’s start with our online learning opportunities, including the Ask the Expert Series.

Clusters and Workstations are usually sized according to one-off benchmarking campaigns during tenders and way before production. While this widely used method is efficient, it has a number of drawbacks: Continue reading
Happy Friday, folks — I’m back! It’s time for my second go at bringing you the latest engineering technology news! But first, it’s Labor Day weekend here in the U.S.- a holiday that traditionally marks the end of summer. So, I wanted to take a moment and wish those of you who will be taking this coming Monday off an enjoyable long weekend! However, I must say that I’m nearly ready for pumpkin spiced coffee and my fall wardrobe! I digress – THE NEWS:

Battery makers are concerned about the potential for fires in the lithium ion batteries used in the latest electric and hybrid vehicles. Two principle mechanisms have been identified that can lead to a cascading reaction known as thermal runaway which in turn can cause battery fires. The first is a short in a cell that may be caused by a crash impact or by an impurity. The second is a blockage or other malfunction in the cooling system that cools the cells by running coolant through microchannels in the battery. There are hundreds of different variables involved in battery design that interact in complex ways that can affect the potential for thermal runaway as well as having an important effect on the efficiency of the battery. Cell and pack makers perform a considerable amount of testing during the development process to investigate the impact of these variables but there is never enough time to come anywhere close to investigating the complete design space. Physical testing is also quite limited in its ability to evaluate battery performance under extreme conditions such as vehicle crashes. Continue reading
