Locally equilibrated stress recovery for goal oriented error estimation in the extended finite element method
Octavio Andrés González Estrada, Juan José Ródenas García, Stéphane Bordas +3
Goal oriented error estimation and adaptive procedures are essential for the accurate and efficient evaluation of numerical simulations that involve complex domains. By locally imp…
Report: Error estimation of recovered solution in FE analysis
Enrique Nadal Soriano, Octavio Andrés González Estrada, Juan José Ródenas García +1
The recovery type error estimators introduced by Zienkiewicz and Zhu use a recovered stress field evaluated from the Finite Element (FE) solution. Their accuracy depends on the qua…
Mesh adaptivity driven by goal-oriented locally equilibrated superconvergent patch recovery
Octavio Andrés González Estrada, E. Nadal, J. J. Ródenas +3
During the last decade there has been an increase on the use of goal-oriented error estimates which help to quantify and control the local error on a quantity of interest (QoI) tha…
