Some Incipient Techniques For Improving Efficiency in Computational Mechanics

Auteur
AMMAR, Amine CHINESTA SORIA, FranciscoRésumé
This contribution presents a review of different techniques available for alleviating simulation cost in computational mechanics. The first one is based on a separated representation of the unknown fields; the second one uses a model reduction based on the Karhunen-Loève decomposition within an adaptive scheme, and the last one is a mixed technique specially adapted for reducing models involving local singularities. These techniques can be applied in a large variety of models.
