Fluid dynamics simulation acquisition

| Information and Communication Technology

Dassault Systèmes acquires Exa bringing mathematical modelling and fluid dynamics simulation into its design platform portfolio.

Dassault Systèmes and simulation software company, Exa Corporation have signed a definitive merger agreement for Dassault Systèmes to acquire Burlington, Massachusetts-based Exa. With the addition of Exa, Dassault Systèmes’ 3DExperience platform will provide customers with a proven, diverse portfolio of combined Lattice Boltzmann fluid simulation technologies, as well as Exa’s fully industrialised systems and nearly 350 highly experienced simulation professionals. This solves challenging fluids problems faster and more accurately than traditional methods for aerodynamics, aeroacoustics, thermal management and a growing list of applications in other industries.

Industrial fluid dynamics

Exa’s software is used by designers and engineers at more than 150 companies in transport and mobility, as well as aerospace and defence, natural resources and others to evaluate highly dynamic fluid flow throughout the design process. Many transport and mobility manufacturers use Exa’s products to simulate aerodynamic flow, aeroacoustics and thermal management.

Simulation of fluid flow, such as the cooling of an engine or the lift of a wing, is a necessary component of simulating the physical behaviour of products, nature and life. For the many situations where fluid flow conditions change rapidly, simulation of dynamically variable flows is critical to achieving accurate assessments of a product and its behaviour in its environment. For these applications, the combination of Exa’s accuracy and timeliness provides results that are superior to those of alternative fluid simulation methods.

Product integration

While providing continuity for Exa’s customers, Dassault Systèmes will integrate Exa’s products into its existing portfolio of industry software. This will offer a new industry standard in multiphysics and multiscale simulation. Combining the two companies greatly enhances collaboration with customers, facilitating the ability to offer integrated products and simplify both commercial and technical interactions. Customers will be able to quickly create and analyse fluid behavioural models that simulate highly dynamic fluid flow across a wide range of applications.

“Both Dassault Systèmes and Exa believe in the value of an integrated focus on science and industry. It is a critical part of our commitment to delivering 3DExperience environments that harmonise products, nature and life. Simulation of dynamic fluid flow is an important part of our multiphysics and multiscale simulation strategy,” said Bernard Charlès, Vice Chairman and CEO, Dassault Systèmes. “With Exa’s valuable application knowledge in transport and mobility and other industry areas, we will accelerate our delivery of industrial products to benefit our existing and future customers.”

“Exa’s proven Lattice Boltzmann simulation technology and extensive professional and industrial expertise are why we’ve been successful in the highly dynamic flow simulation market,” said Stephen Remondi, President and Chief Executive Officer of Exa Corporation. “Becoming part of Dassault Systèmes’ 3DExperience platform and Simulia portfolio will bring enormous value to our customers in all industries.”

Completion of the transaction is expected in the fourth quarter of 2017.
