AMG/FOSLS for LLNL Applications
Marian Brezina, Jim E. Jones · 2001
The work included improving parallel scalability of the multilevel software package ML, and concentrated on improving robustness and convergence properties of the Smoothed Aggregation Multilevel Iterative Solver (SAMISdat(AMG)) for solution of second order problems. Although both scalar and nonscalar problems were targeted, the emphasis was on treatment of nonscalar problems of thin body elasticity such as encountered with ALE3D.
