Aggregation in the generalized transportation problem

Refinamiento h-adaptativo de mallas no estructuradas en problemas estacionarios y transitorios de flujos compresibles
(2009-06-24)
An adaptive refinement strategy to solve steady and unsteady compressible non- viscous flows by the finite element method over unstructured meshes is developed. The quality of the adapted mesh is the main driving force to ...
A Priori and a Posteriori Error Analyses of an Augmented HDG Method for a Class of Quasi-Newtonian Stokes Flows
(Springer, 2016-12)
In a recent work we developed a new hybridizable discontinuous Galerkin (HDG) method for a class of nonlinear Stokes models arising in quasi-Newtonian fluids. The approach there uses the incompressibility condition to ...
Towards fully computable error bounds for the incompressible navier-stokes equatións
(2012)
We obtain fully computable constant free a posteriori error bouncls on simplicial meshes for: a nonconforming finite element approximations for a Stokes problem and a low-orcler conformingancl low-orcler stabilizecl ...
Analysis of an adaptive HDG method for the Brinkman problem
(2018)
We introduce and analyze a hybridizable discontinuous Galerkin method for the gradient-velocity-pressure formulation of the Brinkman problem. We present an a priori error analysis of the method, showing optimal order of ...
HIGH-ORDER MIXED METHODS IN CONTINUUM MECHANICSMÉTODOS MIXTOS DE ALTO ORDER EN MECÁNICA DEL MEDIO CONTINUO
(2019)
The aim of this thesis is to develop high order mixed finite element discretizations for the numerical solution of partial differential equations arising from continuum mechanics, focusing on scenarios in which our methods ...
