AN ACA ACCELERATED ISOGEOMETRIC BOUNDARY ELEMENT ANALYSIS

This paper presents an adaptive cross approximation (ACA) accelerated Isogeometric Boundary Element Method (IBEM) using Non-Uniform Rational B-Splines (NURBS) as shape and interpolation functions. Provided that NURBS are used in CAD programs to describe geometry, the mesh generation in the IBEM is n...
