A simple method for animation of water waves is presented. The two-dimensional wave equation with damping is used to obtain a finite difference scheme for height distribution. A computational procedure employs explicit time integration. High frame rates are typically obtained for real-time animation of water waves.
This article presents special quadrilateral quadratic refinement elements, which provide geometry and field continuity across T-junctions where two elements are connected to one side of a larger quadri-lateral. The main idea in element refinement is to place one or more nodes outside the element area and to modify element shape functions in order to… (More)
