A Spectral Projection Preconditioner for Solving Ill Conditioned Linear Systems
Man-Chung Yeung, Craig C. Douglas, Long Lee
We present a preconditioner based on spectral projection that is combined with a deflated Krylov subspace method for solving ill conditioned linear systems of equations. Our result…
On Solving Ill-Conditioned Linear Systems
Craig C. Douglas, Long Lee, Man-Chung Yeung
This paper presents the first results to combine two theoretically sound methods (spectral projection and multigrid methods) together to attack ill-conditioned linear systems. Our…
Condition number estimates for matrices arising in NURBS based isogeometric discretizations of elliptic partial differential equations
Krishan P. S. Gahalaut, Satyendra K. Tomar, Craig. C. Douglas
We derive bounds for the minimum and maximum eigenvalues and the spectral condition number of matrices for isogeometric discretizations of elliptic partial differential equations i…
A wildland fire model with data assimilation
Jan Mandel, Lynn S. Bennethum, Jonathan D. Beezley +4
A wildfire model is formulated based on balance equations for energy and fuel, where the fuel loss due to combustion corresponds to the fuel reaction rate. The resulting coupled pa…
