Webis described. The method is based on the streamline curvature velocity equation. Sev-eral examples illustrating this method are presented and discussed. INTRODUCTION A … WebThis is a method that treats the free surface as a sharp interface whose motion is followed. In this method, boundary-fitted grids are used and advanced each time the free surface is moved. Interface tracking method is useful in situations like calculation of flow around submerged bodies. This is done by making an unperturbed free surface ...
