Exa Corporation (Exa) is engaged in developing, selling and supporting simulation software and services that vehicle manufacturer�s use. The Company�s solutions enable engineers and designers to augment or replace conventional methods of evaluating designs that rely on expensive and inefficient physical prototypes and test facilities with accurate digital simulations. The Company is primarily focused on the ground transportation market, but is also beginning to focus in the aerospace, oil and gas production, chemical processing, architecture, engineering and construction, power generation, biomedical and electronics industries. The Company�s product, PowerFLOW, is a software solution for fluid flow problems, including aerodynamics, thermal management, and aeroacoustics, or wind noise. PowerFLOW relies upon its technology Digital Physics, which is based on algorithms known as the lattice Boltzmann method.
