  2. 1. Postprocessing Techniques and Adaptivity in the Finite Element Method

    Author : Fethi Abdulwahab; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; error estimation; postprocessing; adaptivity; superconvergence; finite element;

    Abstract : The Finite Element (FE) method is an approximate method and as such the accuracy of its solutions must be controlled to allow for a reliable application. This thesis deals with error estimation and improvements of the FE solutions based on superconvergent properties of the FE solution in certain points. READ MORE
