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