What is... the Adaptive Finite Element Method?

This page hosts information on Joscha Gedicke's talk "What is ... the Adaptive Finite Element Method?" at the WhatIsSeminar.


The Adaptive Finite Element Method (AFEM) is a powerful tool for numerical simulations. It is used to solve various problems of different kind numerically with high accuracy but less computational effort. This introductory talk explains key terms such as linear finite elements, a posteriori error estimators and adaptive mesh refinement. For a simple Poisson model problem the basic analytical setting such as the variational formulation is explained. The linear finite elements lead to a numerical discretization of the variational equation. In order to save computational time it is important to involve adaptivity into the algorithms. It will be explained what adaptivity means and how adaptive mesh refinement and a posteriori error estimators lead to the AFEM.


can i have this talk? and i need the contact of Joscha Gedicke for further information rgul@zedat.fu-berlin.de
