Computation of Nonlinear Free-Surface Flows by a Meshless Numerical Method
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 134, Issue 2
Abstract
A meshless numerical model for nonlinear free surface water waves is presented in this paper. Using the fundamental solution of the Laplace equation as the radial basis functions and locating the source points outside the computational domain, the problem is solved by collocation of boundary points. The present model is first applied to simulate the generation of periodic finite-amplitude waves with high wave steepness and then is employed to simulate the modulation of monochromatic waves passing over a submerged obstacle. Very good agreements are observed when comparing the present results with an analytical solution, experimental data, and other numerical results.
