ABSTRACT
This article gives the basics for finite element problems related to meshes. We are interested in the definition of a mesh. Thanks to the notion of metric, the geometric point of view is replaced by an algebraic and analytical point of view allowing to unify the notions of mesh, mesh adaptation and remeshing. In this new concept, a mesh is only a Riemannian space in which the metrics characterize the elements.
