OpenFOAM – errorEstimate

Dans cet article, nous proposons une version légèrement modifiée d’un estimateur d’erreur proposé par le fork foam-extend.

Il s’agit d’un estimateur d’erreur en résidu qui permet d’estimer l’erreur de discrétisation due à la méthode des volumes finis
sur les éléments d’un maillage 2D ou 3D. Pour plus d’informations sur les estimateurs d’erreur, on pourra se reporter aux travaux de H. Jsak ou encore dans le secteur de la mécanique des milieux continus à la documentation de Code_Aster.

Cette version de l’estimateur d’erreur recodée pour être compatible avec OpenFoam v5.0 et disponible ici l’est à titre indicatif et doit encore être validé.
