IGA is a new and innovative computational approach within Finite Element Analysis, which allows performing simulations of structural behaviour directly on the NURBS parametrization of CAD geometry objects.

L'analyse isogéométrique (AIG) (isogeometric analysis, IGA) est une méthode de calcul numérique dont le développement a commencé en 2005 et consistant à utiliser des splines, et plus généralement des NURBS, dans la méthode des éléments finis (MÉF). (Wikipedia, CC BY-SA)
