TetrUSS is a time-tested computational fluid dynamics toolset serving the configuration aerodynamics needs of NASA’s aeronautics and exploration programs. Present capabilities include rapid grid generation, inviscid and viscous flow analysis and design, special boundary conditions, and ease of use.

TetrUSS has a rich history of innovation over the past two decades. It has left a wide footprint across many NASA programs and industry projects, including the NASA Aviation Safety Program, Environmentally Responsible Aircraft Project, Commercial Supersonic Technology Project, and the NASA Constellation Program. Computational aerodynamic support is currently being provided to the upcoming NASA flight demonstration projects under the Advanced Air Vehicles Program.

TetrUSS was the 1996 and 2004 recipient of the NASA Software of the Year award and the recipient of the 2004 Apple Design Award for the Best Mac OS X Scientific Computing Solution.
