The Exa product suite is designed to provide a complete solution for executing the simulation-based design process. It includes the PowerFLOW® simulation engine, automatic fluid grid generation engine, as well as mesh preparation, advanced simulation analysis, and rapid design geometry modification products. The software is delivered in a client/server architecture in which the computationally intensive grid generation and simulation processes run on a centralized massively parallel multi-processor server, while the interactive applications for simulation preparation and post-processing analysis run on desktop clients that interact with the central server.
Through the usage of our unique, inherently transient Lattice Boltzmann-based physics, Exa’s PowerFLOW® CFD solution performs simulations that accurately predict real world conditions. Using the PowerFLOW suite, engineers evaluate product performance early in the design process prior to any prototype being built – when the impact of change is most significant for design and budgets. PowerFLOW imports fully complex model geometry and accurately and efficiently performs aerodynamic, aeroacoustic and thermal management simulations.
