(Universitat Politècnica de Catalunya, 2009)
Article
Accés obertEn este trabajo se introduce un nuevo estimador de error residual explícito a posteriori para problemas elípticos orientado a cantidades de interés. Se propone utilizar funciones burbuja sobre elementos y sobre aristas. ... -
Goal-oriented adaptivity for shell structures: error assessment and remeshig criteria
(2003-12)
Article
Accés restringit per política de l'editorialThe reliable computation of shell structures requires a tool to assess and control the quality of the finite element solution. For practical purposes, the quality of the numerical solution must be measured using a quantity ... -
Goal-oriented h-adaptivity for the Helmholtz equation: error estimates, local indicators and refinement strategies
(2011-01-14)
Article
Accés obertThis paper introduces a new goal-oriented adaptive technique based on a simple and effective post-process of the finite element approximations. The goal-oriented character of the estimate is achieved by analyzing both the ...
