Abstract:

Based on the multiblock structured grids, the parallel algorithm for the fully implicit unfactored method of Euler equations is studied in the paper. In order to promote the parallel efficiency, a load balancing method is presented. The statistics of wall time and the parallel efficiency after balancing all show the effectiveness of the method. For the property of the largescale parallel computers, a method of estimating the computing and communication time cost is obtained based on the least mean square approximation.
