RIA: Development of an Implicit CFD Algorithm for Distributed Memory Parallel Computers

这项研究的主要目标是将一种有前景的计算流体动力学 (CFD) 新算法应用于分布式内存并行计算机。 长期目标是显着增加具有工业意义的流动问题的规模，这些问题可以在经济实惠的高性能机器上进行常规模拟。 所选择的 CFD 算法称为 BLIMM（块隐式多重网格方法），已被证明对于求解具有大量网格点的网格上的再循环、不可压缩流非常有效。 该算法基于控制体积有限差分法，该方法是多种商业和工业 CFD 代码的基础。//

The primary objective of this research is to apply a promising new algorithm for computational fluid dynamics (CFD) to a distributed memory parallel computer. The long range goal is to significantly increase the size of flow problems of industrial significance that can be routinely simulated on affordable, high-performance machines. The chosen CFD algorithm , called BLIMM for Block-Implicit Multigrid Method, has been shown to be very efficient for solving recirculating, incompressible flows on meshes with large numbers of grid points. The algorithm is based on the control-volume finite- difference method, which is the basis of several commercial and industrial CFD codes.//
