描述了拖拽polaranalysiscapabilityforthree-dimensionalhigh-liftcone轨迹的完整步骤。该方法基于非结构化网格的使用，使得在高扬程锥形网格中出现的复杂几何形状能够快速周转。特别注意创建一种能够在高分辨率网格上进行分析的功能。数百万个顶点的非结构网格最初是在工作站上生成的，随后在超级计算机上重新生成。在大型并行计算机上，采用非结构凝聚多重网格算法在这些网格上进行求解。在使用高达24：7 GB 106个网格点的运输起飞锥形上，很好地预测了整个入射范围内的升力和阻力。在现有并行机上的生产环境中使用这种方法的可行性，以及在使用多达1450个处理器的机器上求解器的可扩展性。
Acompletegeometryto drag polaranalysiscapabilityforthree-dimensionalhigh-liftcone gurationsisdescribed. The approach is based on the use of unstructured meshes to enable rapid turnaround for complicated geometries that arise in high-lift cone gurations. Special attention is devoted to creating a capability for enabling analyses on highly resolved grids. Unstructured meshes of several million vertices are initially generated on a workstation and subsequently are ree ned on a supercomputer. The e ow is solved on these ree ned meshes on large parallel computers using an unstructured agglomeration multigrid algorithm. Good prediction of lift and drag throughout the range of incidences is demonstrated on a transport takeoff cone guration using up to 24 :7 £ 10 6 grid points. The feasibility of using this approach in a production environment on existing parallel machines is demonstrated, as well as the scalability of the solver on machines using up to 1450 processors.
