Abstract

A methodology for large-scale structural analysis using a parallel frontal solution algorithm is developed and implemented on the Alliant FX/80 Multiple Instructions Multiple Data (MIMD) parallel computer. In this solution scheme the well-known frontal method of finite element analysis is adapted to a parallel environment. In a frontal method, the joint assembly and elimination processes are carried out simultaneously. A degree-of-freedom is eliminated from the system equations as soon as the stiffness contributions from all adjacent elements to that degree-of-freedom have been accounted for. Since the global stiffness matrix is never formed, the amount of core storage requirement is small and large-scale structures can be analyzed efficiently.
