The next-generation software CODA (CFD ONERA DLR Airbus) was launched to overcome the limitations of CFD tools currently used in the aerospace industry and to enable rapid and reliable evaluations of innovative configurations. This software already incorporates cutting-edge technologies that will be continuously developed collaboratively and deployed in design process for the production of innovative configurations that address aeronautical challenges, particularly those defined by the Strategic Research and Innovation Program for Clean Aviation (SRIA). CODA integrates classical finite volume (FV) methods as well as new discontinuous Galerkin (DG) methods, which have been studied for nonlinear CFD for nearly twenty years and have undergone extensive evaluation at international workshops. This contribution highlights recent research and development conducted at ONERA to improve simulation accuracy using modal DG and DGSEM methods, and efficiency through new linear and nonlinear solvers.

摘要

The next-generation software CODA (CFD ONERA DLR Airbus) was launched to overcome the limitations of CFD tools currently used in the aerospace industry and to enable rapid and reliable evaluations of innovative configurations. This software already incorporates cutting-edge technologies that will be continuously developed collaboratively and deployed in design process for the production of innovative configurations that address aeronautical challenges, particularly those defined by the Strategic Research and Innovation Program for Clean Aviation (SRIA). CODA integrates classical finite volume (FV) methods as well as new discontinuous Galerkin (DG) methods, which have been studied for nonlinear CFD for nearly twenty years and have undergone extensive evaluation at international workshops. This contribution highlights recent research and development conducted at ONERA to improve simulation accuracy using modal DG and DGSEM methods, and efficiency through new linear and nonlinear solvers.
