PITTSBURGH and SAN DIEGO, Jan. 3, 2014 (GLOBE NEWSWIRE) -- ANSYS (Nasdaq:ANSS), a global leader and innovator of engineering simulation software, announced today that it has completed the acquisition of Reaction Design, a leading developer of chemistry simulation software. The Company will provide further details regarding the transaction and its impact on the 2014 financial outlook at the time of its 2013 year-end earnings announcement. Headquartered in San Diego, Reaction Design has about 25 employees and more than 400 customers around the world. Its flagship product, CHEMKIN-PRO, is the gold standard for modeling and simulating gas-phase and surface chemistry. The combination of ANSYS' proven computational fluid dynamics (CFD) solutions with Reaction Design's industry-leading chemistry solvers will provide the best-in-class combustion simulation tools available on the market. Understanding and predicting the effects of chemistry in a combustion system is critical to developing competitive products in transportation, energy and materials processing applications. Relying on experimental testing alone for accurate performance validation is inadequate, given today's complex designs and shortened design cycles. Effective simulation of the underlying detailed chemistry is critical to advancements in engine and fuel technology. Reaction Design's solutions enable transportation manufacturers and energy companies to rapidly achieve their clean technology goals by automating the analysis of chemical processes via computer simulation and modeling solutions. The acquisition of Reaction Design complements ANSYS' offering for the simulation of internal combustion engines, leading to improved fuel efficiency.
