Abstract:

The innovation of our Phase II STTR program is to develop and provide to NASA automatic mesh generation software for the simulation of fluid flows using Reynolds-Averaged Navier-Stokes codes. As a result of the successful Phase I work, these new tools are now capable of generating high-quality, highly-stretched (anisotropic) meshes in boundary layer regions and transition smoothly to inviscid flow regions, even in an adaptive context. The significance is that our method has the ability to generate a boundary layer mesh while keeping intact the previous adaptation procedures from non viscous simulations. This leads to a natural coupling between boundary layer mesh generation and anisotropic mesh adaptation. All of the Phase I objectives were met and all tasks were completed successfully. The Phase II project will include improvements in surface remeshing, coding for optimal speed and increased robustness of the solvers, adding a mesh optimization module, providing a link to general CAD packages, include unsteady coupling where the boundary layer mesh refinement evolves in time, conduct further validation and verification on NASA models by running flow cases with our solver, documenting the project, and delivering the new meshing software to NASA.
