TL;DR: This study considers multiphysics applications from algorithmic and architectural perspectives, where “algorithmic” includes both mathematical analysis and computational complexity, and “architectural’ includes both software and hardware environments.
Journal ArticleDOI
Nonlinearly Preconditioned Inexact Newton Algorithms
Xiao-Chuan Cai,David E. Keyes +1 more
TL;DR: A nonlinear additive Schwarz-based parallel nonlinear preconditioner is proposed and studied and it is shown numerically that the new method converges well even for some difficult problems, such as high Reynolds number flows, where a traditional inexact Newton method fails.
