Simulation-Driven Design for Product Engineering


Exa provides software products and services for simulation-driven design. Leading manufacturers use Exa’s fluid flow, heat transfer, and acoustic simulation solutions to optimize the performance of their products, reduce product development costs, and improve the efficiency of their design and engineering processes.


Simulation-driven design enables engineers to predict product performance early in the design process, reducing late-stage design changes and reducing or eliminating expensive physical prototypes and tests. Exa’s solutions encourage rapid iteration between design and analysis. They provide critical insight into how potential design variations impact the range of possible performance and enables the discovery of solutions that optimize the trade-offs between competing design and engineering constraints and requirements.


"We used Exa’s PowerFLOW transient solver that directly resolves very large eddies to deliver superior accuracy compared to conventional CFD codes. This approach is especially beneficial in areas where flow physics are complex such as in the rear of a curved vehicle. The result is a full-size electric sedan with a drag coefficient of 0.24.

"We are raising the bar with full-scale simulations....The simulations of the full-scale aircraft with noise reduction concepts will help recover a significant part of the loss of the flight test. In addition, the simulations provide valuable insights into the sources of airframe noise.

"The slightest shift in the curve of the headlights, the shape of the fender, or the angle of the mirrors can dramatically alter a truck's business value. Take that mudflap, for example: A little haircut added an extra half-percent of fuel efficiency to the T660. It is one of several tweaks that could save a 1,000-truck fleet $1 million a year. "
