Enabling New Flexibility in the SUNDIALS Suite of Nonlinear and Differential/Algebraic Equation Solvers.
TL;DR: The SUNDIALS suite of nonlinear and DIfferential/ALgebraic equation solvers (SUNDIALs) as mentioned in this paper has been redesigned to better enable the use of application-specific and third-party algebraic solvers and data structures.
Journal ArticleDOI
Newton–Krylov-multigrid solvers for large-scale, highly heterogeneous, variably saturated flow problems
Jim E. Jones,Carol S. Woodward +1 more
TL;DR: A class of solvers developed for the parallel solution of Richards' equation, a model used in variably saturated flow simulations, takes advantage of the fast, robust convergence of globalized Newton methods as well as the parallel scalability of multigrid preconditioners.

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
Proof of concept of regional scale hydrologic simulations at hydrologic resolution utilizing massively parallel computer resources
Stefan Kollet,Reed M. Maxwell,Carol S. Woodward,Steve Smith,Jan Vanderborght,Harry Vereecken,Clemens Simmer +6 more
TL;DR: This study demonstrates that regional scale hydrology simulations on the order of 103 km2 are feasible at hydrologic resolution with reasonable computation times, which has been previously assumed to be an intractable computational problem.
