Multilevel acceleration of scattering-source iterations with application to electron transport
Nuclear Engineering and Technology, 2017 Acceleration/preconditioning strategies available in the SCEPTRE radiation transport code are described. A flexible transport synthetic acceleration (TSA) algorithm that uses a low-order discrete-ordinates (SN) or spherical-harmonics (PN) solve to ...

On numerical solution of nonlinear parabolic multicomponent diffusion-reaction problems
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 This work continues our previous analysis concerning the numerical solution of the multi-component mass transfer equations. The present test problems are two-dimensional, parabolic, non-linear, diffusion- reaction equations. An implicit finite difference

A Randomized Q-OR Krylov Subspace Method for Solving Nonsymmetric Linear Systems
MathematicsThe most popular iterative methods for solving nonsymmetric linear systems are Krylov methods. Recently, an optimal Quasi-ORthogonal (Q-OR) method was introduced, which yields the same residual norms as the Generalized Minimum Residual (GMRES) method ...

Comparison of different iterative schemes for ISPH based on Rankine source solution
International Journal of Naval Architecture and Ocean Engineering, 2017 Smoothed Particle Hydrodynamics (SPH) method has a good adaptability for the simulation of free surface flow problems. There are two forms of SPH. One is weak compressible SPH and the other one is incompressible SPH (ISPH).

Método GMRES(m) pré-condicionado com a estrutura de dados CSR
Cadernos CajuínaTem-se que os métodos iterativos são mais eficientes que os métodos diretos na resolução de sistemas lineares e esparsos. Saad e Schultz (1986) propuseram o método GMRES reinicializado que é alvo de muitas pesquisas.
