Abstract
COFFE is the finite-element flow solver within HPCMP CREATE™-AV Kestrel. Kestrel supports a range of flow solver fidelity options to support the DoD acquisition community, and COFFE targets the need for high-fidelity flow solutions. Recent Kestrel development has made COFFE easier for users to access, has provided users with the IDDES turbulence treatment and mesh motion capabilities that they may be accustom to using with KCFD simulations, and has significantly sped up high-order time-accurate simulations through the use of RungeKutta stage-value predictors. These improvements are demonstrated on a variety of real-world geometries, including the ROBIN-mod7 fuselage, the F-16XL-1, and the Sikorski S-76 rotor in hover, as well as the more academic transonic axisymmetric hump of Bachelo and Johnson, which provides a targeted test of the ability to simulate complex, unsteady shock-wave/boundarylayer interactions. This paper concludes with a discussion on the future development directions of the COFFE solver.
