A Fast Solver Free of Fill-In for Finite Element Problems,
Abstract
A new algorithm for solving FEM problems is presented. It blends a preconditioned conjugate gradient iteration into a direct factorization method. The goal was to reduce fill to a negligible level and thus reduce storage requirements but it turned out to be faster than its rivals for an important class of problems. (Author)
