Advances in Adaptive Computational Methods in Mechanics
Main description:
Mastering modelling, and in particular numerical models, is
becoming a crucial and central question in modern computational
mechanics. Various tools, able to quantify the quality of a model
with regard to another one taken as the reference, have been
derived. Applied to computational strategies, these tools lead to
new computational methods which are called "adaptive".
The present book is concerned with outlining the state of the art
and the latest advances in both these important areas.Papers are
selected from a Workshop (Cachan 17-19 September 1997) which is the
third of a series devoted to Error Estimators and Adaptivity in
Computational Mechanics. The Cachan Workshop dealt with latest
advances in adaptive computational methods in mechanics and their
impacts on solving engineering problems. It was centered too on
providing answers to simple questions such as: what is being used
or can be used at present to solve engineering problems? What
should be the state of art in the year 2000? What are the new
questions involving error estimators and their applications?
