Self-Organizing Hybrid Cartesian Grid Generation and Solutions for Arbitrary Geometriesflows, the eddy viscosity is calculated using the Spalart-Allmaras turbulence model. The hybrid Cartesian grid is improved due to manifold adaptation features, which are optimized in order to avoid any user interaction. Therefore, the final grid depends only on the particular geometry and flow structure (self-organized grid).作者: Fulsome 時(shí)間: 2025-3-22 15:09 作者: Harridan 時(shí)間: 2025-3-22 20:47
