9.Summary of Research Results

We have developed an advanced parallel computational mechanics system for large scale analysis and design named ADVENTURE. Key technologies employed are (a) module-based architecture, (b) standardization of I/O format and libraries, (c) a parallel solver based on the hierarchical domain decomposition method (HDDM), (d) the parallel domain decomposer and (e) the parallel visualizer. Practical performances of the system are demonstrated through several static and dynamic analyses, and shape optimization calculations of 3D precise models with a half million to 100 million DOF meshes. Owing to excellent performance of the system together with open source strategy, the ADVENTURE system has already started being disseminated into a variety of industries and academia since free release of the β version on 1st Dec. 2001. About 420 registered users in academia and industries have downloaded the programs, and about forty of them are now testing the programs. We confirm that such dissemination would be further accelerated owing to free release of all 18 modules on 1st March 2002.
During the past five years, i.e. the period of the JSPS ADVENTURE project, commodity technology including PC clusters, Linux and MPI have been improved dramatically and been popular everywhere. Furthermore, Grid-computing is about to grow. However, without good application software, these environments do not provide any practical merits to societies. We strongly expect that the ADVENTURE system and its family will become one of key application softwares in such next generation computing environments.
