The unstructured mixed-element cell-centered finite volume flow solver USM3D is enhanced with new capabilities such as line generation for general unstructured grids and optimization of the iterative solver. The efficiency of the new developments is assessed in a massively parallel environment. The assessments are conducted using a baseline method and the recent hierarchical adaptive nonlinear iteration method framework. Three benchmark turbulent flows (namely, a subsonic separated flow around a three-dimensional hemisphere–cylinder configuration, a transonic flow around the ONERA M6 wing, and a supersonic flow through a square duct) are considered.

混合元素 USM3D 用于基准三维流的效率

以单元为中心的非结构化混合元素有限体积流求解器 USM3D 得到了增强,增加了新功能,例如为一般非结构化网格生成线和优化迭代求解器。在大规模并行环境中评估新开发项目的效率。评估是使用基线方法和最近的分层自适应非线性迭代方法框架进行的。考虑了三个基准湍流(即围绕三维半球-圆柱结构的亚音速分离流、围绕 ONERA M6 机翼的跨音速流和通过方形管道的超音速流)。
