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 ... -
Pure Lagrangian and semi-Lagrangian finite element methods for the numerical solution of Navier–Stokes equations
(Elsevier, Institute for Mathematics and Computer Science (IMACS), 2015-05-26)[Abstract]: In this paper we propose a unified formulation to introduce Lagrangian and semi-Lagrangian velocity and displacement methods for solving the Navier–Stokes equations. This formulation allows us to state classical ... -
Second-Order Pure Lagrange-Galerkin Methods for Fluid-Structure Interaction Problems
(SIAM, Society for Industrial and Applied Mathematics, 2015-09-30)[Abstract]: In this paper we propose a second order (both in time and in space) pure Lagrange-Galerkin method for the numerical solution of fluid-structure interaction problems. The proposed scheme is written in material ... -
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 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 ...
