Object-oriented parallelization system for object-oriented CFD simulation system

摘要

The aim of the present study is to reduce the load and the cost of the domain users when the domain users develop the parallel CFD simulation system. To realize this aim, we have developed the object-oriented Parallelization System named the OPS. The OPS generates the source code of the parallel CFD Object-Oriented Simulation System (OOSS) from that of the sequential CFD-OOSS. We have developed the OPS by applying the technology of the automatic distribution system named the ADS. To develop the parallel simulation system, it usually takes over several days or weeks. By using the OPS, however, the user can obtain the parallel CFD-OOSS only in a few minutes for some shortest cases. The restrictions to use this OPS are leniently. At the test uses, the domain users have found out no problems, and the parallel OOSS that is generated by the OPS shows better performance than the automatically distributed OOSS that is generated by the ADS. We can conclude that the OPS is useful and valuable for the domain users from the following three viewpoints: (1) The reduction of the user's load and the cost, (2) The lenient restrictions for the user CFD-OOSS, (3) The comparatively good performance.
