A posteriori error analysis of a semi-augmented finite element method for double-diffusive natural convection in porous media
Álvarez Guadamuz, Mario Andrés; Colmenares García, Eligio Antonio; Sequeira Chavarría, Filander A. (2024)This paper presents our contribution to the a posteriori error analysis in 2D and 3D of a semi-augmented mixed-primal finite element method previously developed by us to numerically solve double-diffusive natural convection ... -
An overlapping preconditioner for 2D virtual problems posed in H(rot) with irregular subdomains
Calvo Alpízar, Juan Gabriel; Herrera Garro, César; Sequeira Chavarría, Filander A. (2022)We present a two-level overlapping Schwarz preconditioner for problems posed in H(rot) in two dimensions, that extends previous methods for Nédélec elements (triangular meshes) to general polygonal partitions (virtual ... -
Analysis of a semi-augmented mixed finite element method for double-diffusive natural convection in porous media
Álvarez Guadamuz, Mario Andrés; Colmenares García, Eligio Antonio; Sequeira Chavarría, Filander A. (2022-05-15)In this paper we study a stationary double-diffusive natural convection problem in porous media given by a Navier-Stokes/Brinkman type system, for describing the velocity and the pressure, coupled to a vector advection-diffusion ...
