2003 journal article

Efficient steady-state solution techniques for variably saturated groundwater flow

ADVANCES IN WATER RESOURCES, 26(8), 833–849.

By: M. Farthing *, C. Kees n, T. Coffey*, C. Kelley n  & C. Miller *

author keywords: Richards' equation; steady-state; pseudo-transient continuation
TL;DR: This work examines the use of pseudo-transient continuation as well as Newton’s method combined with standard globalization techniques for steady-state problems in heterogeneous domains, and investigates the methods’ performance with direct and preconditioned Krylov iterative linear solvers.

2003 article

Globally convergent algorithms for nonsmooth nonlinear equations in computational fluid dynamics

Coffey, T., McMullan, R. J., Kelley, C. T., & McRae, D. S. (2003, March 1). JOURNAL OF COMPUTATIONAL AND APPLIED MATHEMATICS, Vol. 152, pp. 69–81.

By: T. Coffey n, R. McMullan n, C. Kelley n  & D. McRae n

author keywords: pseudo-transient continuation; nonlinear equations; steady-state solutions; global convergence; splitting methods; Euler equations; MUSCL approximation
TL;DR: A nonsmooth discretization of the Euler equations for flow in a nozzle is solved with splitting method which is in turn globalized with the method of pseudo-transient continuation. (via Semantic Scholar)
