Highly scalable parallel computational models for large-scale RTM process modeling simulations. Part 2: Parallel formulation theory and implementation

In Part 2 of this work, we highlight some key elements of the parallel form ulation theory and implementational aspect of process modeling and manufact uring applications of composites with particular emphasis on resin transfer molding (RTM). The approaches for simulating process modeling and manufact uring applications of composites include (I) the traditional explicit contr ol-volume finite-element (CV-FE) approach, and (2) a recently developed and new implicit, pure finite-element (pure FE) approach. SGI Power Challenge and SGI Origin 2000, which are symmetric multiprocessor (SMP) computing pla tforms, are employed in this study. The issues in implementation and softwa re development of these manufacturing process simulations are parallel algo rithm development, data structures, and interprocessor communication strate gies, with emphasis on performance and scalability on these symmetric multi processors. Fundamental concepts and characteristic features of the propose d scalable parallel algorithms are described and developed with theoretical analysis. Whereas the theoretical formulations and generic design presente d in Part I, the parallel theoretical developments are described in Part 2, and the techniques developed are applied to large-scale problems using Pow er Challenge and SGI Origin to demonstrate the effectiveness and the practi cal applicability, which is subsequently presented in Part 3 of this work.
