A Modified Frontal Technique Suitable for Parallel Systems.

Abstract

Frontal techniques offer the potential for processing the assembly and the factorization phases of finite element analysis in parallel systems. However, the rows of the stiffness matrix are assembled and factored in different orders, thus depriving frontal solvers of the uniformity desired in parallel processing. On the other hand, band solution techniques handle the factorization phase in a very uniform way but do not interleave assembly and factorization. This paper, suggests a technqiue that borrows from both frontal and band solvers those characteristics that are advantageous for parallel processing. Moreover, book keeping and data manipulation are simpler in the suggested technique than in the classical frontal method. This makes the suggested technique also attractive for sequential systems.
