000013602 520__ $$2eng$$aWe have been developing a fully parallelized general-purpose finite element analysis system named ADVENTURE since August 1997. The system was designed to be able to analyze a finite element model of arbitrary shape over 100 million DOF mesh [1-4]. The first version of the ADVENTURE system has been released from the project website as open source software since March 2002 [4]. About 33,000 modules have been downloaded and 6,300 registered users in academia and industries are using the programs worldwide, while a private company has developed and released its commercial version named ADVENTUTREcluster [5]. The Hierarchical Domain Decomposition Method (HDDM) with a preconditioned iterative solver, i.e. Balancing Domain Decomposition (BDD), is adopted in the solver module for solid analysis named ADVENTURE_Solid [2-3].    This paper describes several new enhancements of the ADVENTURE system towards Peta-scale computing environments in the following. (1) Implementation of several nonlinear constitutive equations for steel and concrete. (2) Performance tuning of the HDDM-BDD solver for solving several ten billion DOF problems on sub-million core machines. (3) Pre- processing modules for creating such ultra-large scale meshes. (4) Parallel coupling analysis module employing partitioned iterative algorithms [6], ADVENTURE_Coupler for fluid- structure and magneto-structure interactions.
