Extended isogeometric boundary element method (XIBEM) for three-dimensional medium-wave acoustic scattering problems

A boundary element method (BEM), based on non-uniform rational B-splines (NURBS), is used to find solutions to three-dimensional wave scattering problems governed by the Helmholtz equation. The method is extended in a partition-of-unity sense, multiplying the NURBS functions by families of plane wav...
