A locally refined rectangular grid finite element method: application to computational fluid dynamics and computational physics
David P. Young,Robin G. Melvin,Michael B. Bieterman,Forrester T. Johnson,Satish S. Samant,John E. Bussoletti +5 more
TL;DR: A new finite element method for solving important linear and nonlinear boundary value problems arising in computational physics is described, designed to handle general three-dimensional regions, boundary conditions, and material properties.

Parallel Newton--Krylov--Schwarz Algorithms for the Transonic Full Potential Equation
TL;DR: It is demonstrated that NKS, combined with a density upwinding continuation strategy for problems with weak shocks, is robust and economical for this class of mixed elliptic-hyperbolic nonlinear partial differential equations, with proper specification of several parameters.
Study Based on the AIAA Aerodynamic Design Optimization Discussion Group Test Cases
Stephen T. LeDoux,John C. Vassberg,David P. Young,Spencer Fugal,Dmitry S. Kamenetskiy,William P. Huffman,Robin G. Melvin,Matthew F. Smith +7 more
TL;DR: In this paper, three model problems associated with aerodynamic drag minimization are studied and the resulting designed and associated baseline geometries are cross analyzed by several computational fluid dynamics codes, including OVERFLOW, TRANAIR, GGNS, and FLO82.

Application of sparse matrix solvers as effective preconditioners
David P. Young,Robin G. Melvin,Forrester T. Johnson,John E. Bussoletti,Laurence B. Wigton,Satish S. Samant +5 more
TL;DR: A new out-of-core sparse matrix package for the numerical solution of partial differential equations involving complex geometries arising from aerospace applications and is an effective preconditioner for Krylov subspace methods, such as GMRES.
