NURBS-based Isogeometric analysis of standard and phase reduction On-Surface Radiation Condition formulations for acoustic scattering

Abstract

This paper is devoted to the NURBS-based Isogeometric analysis of the On-Surface Radiation Condition (OSRC) method for solving two-and three-dimensional time-harmonic acoustic scattering problems. In addition, a Phase Reduction of the OSRC formulation based on a plane wave ansatz is introduced. This leads to an efficient and accurate implementation of OSRC methods. Some numerical tests for two-and three-dimensional problems illustrate the proposed approach.
