Numerical Analysis of a Second Order Pure Lagrange--Galerkin Method for Convection-Diffusion Problems. Part II: Fully Discretized Scheme and Numerical Results
(SIAM, Society for Industrial and Applied Mathematics, 2012-11-01)[Abstract]: We analyze a second order pure Lagrange-Galerkin method for variable coefficient convection-(possibly degenerate) diffusion equations with mixed Dirichlet-Robin boundary conditions. In a previous paper the ... -
Numerical Approximation of Convection-Diffusion Problems Through the PSI Method and Characteristics Method
(Springer, 2011-01-01)[Abstract]: In this work we present some numerical methods for solving evolutive convection-diffusion problems. In order to obtain a physically admissible solution we search for monotone and accurate methods that are also ...
