Crouzeix–Raviart boundary elements
Numerische Mathematik, 2009 The authors analyze a non-conforming boundary element method with discontinuous elements. More precisely, the use of piecewise linear Crouzeix-Raviart elements where jumps of basis functions across element boundaries have integral mean zero is studied. The meshes are triangular and regular, but the basis functions are not continuous.

Convergence analysis of the scaled boundary finite element method for the Laplace equation [PDF]
, 2020 The scaled boundary finite element method (SBFEM) is a relatively recent boundary element method that allows the approximation of solutions to PDEs without the need of a fundamental solution.

The scs′ Boundary Element: Characterization of Boundary Element-Associated Factors
Molecular and Cellular Biology, 1997 Boundary elements are thought to define the peripheries of chromatin domains and to restrict enhancer-promoter interactions to their target genes within their domains. We previously characterized a cDNA encoding the BEAF-32A protein (32A), which binds with high affinity to the scs' boundary element from the Drosophila melanogaster 87A7 hsp70 locus ...

A Galerkin boundary element method for high frequency scattering by convex polygons [PDF]
, 2007 In this paper we consider the problem of time-harmonic acoustic scattering in two dimensions by convex polygons. Standard boundary or finite element methods for acoustic scattering problems have a computational cost that grows at least linearly as a ...
