Le projet<\/h4>\n

Le laboratoire Paul Painlev\u00e9\u00a0 collabore depuis 2008 avec EDF R&D sur le d\u00e9veloppement d’estimateurs d’erreur a posteriori en \u00e9l\u00e9ments finis. Ces outils num\u00e9riques sont destin\u00e9s \u00e0 am\u00e9liorer la pr\u00e9cision des calculs pour la simulation de champs \u00e9lectromagn\u00e9tiques en r\u00e9gime basse fr\u00e9quence. Ce travail, r\u00e9alis\u00e9 en partenariat avec le Laboratoire d’Electrotechnique et d’Electronique de Puissance de Lille (L2EP) et le laboratoire de Math\u00e9matiques et Applications de Valenciennes (LAMAV), s’est concr\u00e9tis\u00e9 jusque maintenant par 2 th\u00e8ses CIFRE. Outre l’obtention de nouveaux r\u00e9sultats th\u00e9oriques n\u00e9cessaires pour garantir la robustesse de l’approche, les estimateurs obtenus ont \u00e9t\u00e9 impl\u00e9ment\u00e9s dans le code de calcul industriel CARMEL_3D et test\u00e9s sur diverses configurations. L’une des applications particuli\u00e8rement vis\u00e9e concerne le contr\u00f4le non destructif, destin\u00e9 ici \u00e0 d\u00e9celer d’\u00e9ventuelles anomalies au coeur des r\u00e9acteurs nucl\u00e9aires.<\/p>\n
