In this paper, a parallel solution framework for the linear static analysis of large structures on heterogeneous PC clusters is presented. The framework consists of two main steps; data preparation and parallel solution. The parallel solution is performed by a substructure based method with direct solvers. The aim of the data preparation step is to create the best possible substructures so that the condensation times of substructures are balanced. Examples which illustrate the applicability and the efficiency of this approach are presented. In these examples, an existing PC cluster having eight different computers was utilized. © 2006 Civil-Comp Press.
