β¦ Synopsis
This study explores a numerical analysis scheme, the manifold method, within the framework of the partition of unity method. The manifold method is rooted in the discrete element method and has been used in solving discretecontinuum interaction problems. At its core, two meshes are employed in an analysis: the mathematical mesh provides the nodes for building a finite covering of the solution domain and the partition of unity functions; while the physical mesh provides the domain of integration. After providing a geometric interpretation and giving a construct overview, the working of the method is illustrated with a number of examples.

A technique is presented to model arbitrary discontinuities in the "nite element framework by locally enriching a displacement-based approximation through a partition of unity method. This technique allows discontinuities to be represented independently of element boundaries. The method is applied t
In this paper we consider the application of hierarchical functions to base approximations which are a partition of unity. The particular hierarchical functions used are added to base finite element interpolations which, for Co approximations, are a particular case of the partition of unity. We also
