Wave diffraction by a harbour with circular arc profile by scaled boundary FEM
In this paper, wave diffraction by a harbour with circular arc profile is studied by the scaled boundary finite-element method (SBFEM), a novel semi-analytical approach, with the combined advantages of both finite-element and boundary-element methods. The governing partial differential equation is w...
