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 ...
Pure Lagrangian and Semi-Lagrangian Finite Element Methods for the Numerical Solution of Convection-Diffusion Problems
(University of Alberta, Northwestern Polytechnical University, Institute for Scientific Computing, 2014)
[Abstract]: In this paper we propose a unified formulation to introduce and analyze (pure) Lagrangian and semi-Lagrangian methods for solving convection-diffusion partial differential equations. This formulation allows us ...
Numerical Analysis of a Second order Pure Lagrange–Galerkin Method for Convection-Diffusion Problems. Part I: Time Discretization
(SIAM, Society for Industrial and Applied Mathematics, 2012-04-17)
[Abstract]: We propose and analyze a second order pure Lagrangian method for variable coefficient convection-(possibly degenerate) diffusion equations with mixed Dirichlet-Robin boundary conditions. First, the method is ...
