Isogeometric boundary element analysis of liquid nonlinear sloshing in two dimensional rectangular tanks

This paper presents a numerical model based on the Isogeometric Analysis (IGA), Boundary Element Method (BEM) and the second order Runge–Kutta (RK2) method for solving the nonlinear sloshing problem in a two-dimensional (2D) tank. In this study, the IGABEM is employed to solve the Laplace equation for the velocity potentials of the liquid, and the singular integral is calculated by the Radial Integral Method (RIM). The Semi-Lagrange (SL)...
