Abstract
In recent years, many structural and fluid analysis programs are parallelized. The authors have been developing fluid analysis programs using MPS method(Moving Particle Semi-implicit Method). In this study, the authors investigate the proportions of the processes in the MPS code. Based on the above investigation, a parallel solver with variables of the distributed coefficient matrix is developed. In order to evaluate the performance of a parallel program, the parallel efficiency of solver and parallel efficiency of searching particles function are measured using test calculations. One million particles are used for the analyses of water collapse and tsunami to demonstrate the performance of a large scale problem.
