In this paper we introduce the concept of dual compatible (DC) splines on nontensor product meshes, study the properties of this class, and discuss their possible use within the isogeometric framework. We show that DC splines are linear independent and that they also enjoy good approximation properties. © Springer International Publishing Switzerland 2014.
