Dassault Systemes Acquiring Exa for CFD

Thursday, October 5th, 2017

It seems that a lot of CAD companies have taken a greater interest in digital simulation the past several years. Case in point — the recent MSC Software acquisition by Hexagon. That high level of interest was again evidenced this week as Dassault Systèmes and Exa Corporation with its simulation software for product engineering, announced the signing of a definitive merger agreement for Dassault Systèmes to acquire Exa. Under the terms of the merger agreement, this represents a value for Exa of approximately $400 million. Exa’s fiscal year ended January 31, 2017 and its revenue was $72 million.

With the addition of Exa, Dassault Systèmes’ 3DEXPERIENCE platform will provide customers with a mature, diverse portfolio of combined Lattice Boltzmann fluid simulation technologies, as well as Exa’s fully industrialized solutions and approximately 350 experienced simulation professionals. Because of its solving method, Exa’s solutions can solve fluids problems faster and more accurately than traditional methods for aerodynamics, aeroacoustics, and thermal management.

Aston Martin Resurrects Its Racing Heritage with Creo

Wednesday, August 22nd, 2012

For almost 100 years, Aston Martin has been an icon of automotive speed and sophistication, winning the most distinctive races in the world throughout the 1920s (French Grand Prix), 1930s (Biennial Cup at Le Mans), and 1940s, as well as the 1950s (Le Mans 24 Hours).

But, for more than 45 years, Aston Martin stayed away from the racetrack.

In 2005, however, the company resurrected its racing heritage when it returned to the world circuit as Aston Martin Racing (AMR). That first year out, AMR’s DBR9 gained a CT1 class victory. Two years later, Aston Martin triumphed at Le Mans. Based on the Aston Martin DB9 road car, the DBR9 retains the chassis, engine block, and cylinder heads of the road car’s V12 engine. The rest of the car was re-engineered for high performance competition use. The DBR9’s bodywork is a blend of optimum aerodynamic performance and the styling of the DB9 road car.

More recently, AMR has geared up with some extra digital technology in its pocket. For a car company like Aston Martin, where prestige and precision have been part of its heritage since 1913, going digital for design and engineering was a big step forward.

After an extensive benchmarking process, AMR chose PTC Creo and PTC Windchill in 2011 for 3D CAD design of its racing vehicles and for PLM in its racecar division.

With the Creo suite, Aston Martin can start with simple sketched designs, refine them in Creo Parametric, and make them work on the track. AMR performs CFD analysis in Creo early on, and designers can make designs more aerodynamic. Instead of waiting for expensive prototypes, problematic areas are now digitally tested and corrected early in the design process using Creo.

In a three-minute video, PTC interviews Rick Simpson, Design Engineer at Aston Martin Racing. He explains the specifics of how PTC’s Creo design toolset helps them reduce lead times from design and fix design issues before going into manufacturing.

Interesting stuff from a company with a large legacy, long period away, and resurrection on the racetrack.
