A development of isogeometric boundary element method for 3D acoustics and its application to shape sensitivity analysis

Abstract

Following our previous work, we first overview the formulation of the isogeometric boundary element method (IGBEM) for 3D Helmholtz equation and its application to the shape sensitivity analysis. Then, after investigating the accuracy of the IGBEM, we apply the IGBEM to solve a scattering problem and shape sensitivity analyses when the shape of boundary is relatively complicated.
