According to the concept of isogeometric analysis(IGA),Non-Uniform Rational B-splines(NURBS)are used to describe the geometry and approximate the physical fields.
The BEM has emerged as a powerful numerical tool for several decades to solve many engineering problems,especially the acoustic and electromagnetic wave propagation problems.
In this paper,the recently developed hybrid numerical method based on isogeometric analysis(IGA)and boundary element method(BEM),named as IGABEM,is further extended to study steady and transient heat
This work applies acoustic topology optimization technique for structure surface design with porous materials,where the fast multipole boundary element method(FMBEM)is employed for sound scattering an
