| Abstract: | A finite element fluid analysis code, which is based on an element-by-element scheme and the matrix-storage free formulation, is developed and implemented to the massively parallel computer; KSR1. Since the element-by-element scheme coupled with the CG-type iterative solver is suitable for parallel processing, the matrix-storage free formulation will enable the large-scale computation within a reasonable time.After the verification of the code by some numerical examples, the cavity flow and cyclinder flow, the parallel efficiency is discussed. In the analysis of cavity flow, the speed-up using 16 CPUs is 15.35, which corresponds to the parallel efficiency of 95.9%. |
