Parallel Computing for Surface Inundation with Local Grid Refinement
Wei‐Hsien Teng, Shiuan-Hung Chen, Ming‐Hsi Hsu · 2001
A local grids-refined method has been developed for a two-dimensional surface inundation simulation with the help of the parallel computing technique to solve the detailed inundation depths and velocities in a mild-slope alluvial plain. The Miau-Li Station of the Taiwan High Speed Rail System (THSRS) is selected as the study area. Two numerical resolutions are adopted in the model are solved by two individual processors. The coarser grid is used for global domain computation, and the finer one is for local region computation around the station. The processors compute the domains in parallel and communicate each other through the Message Passing Interface (MPI). Under the same numerical result, the computation time is efficiently shortened when parallel computing is employed than the sequential computing.
