β¦ Synopsis
New finite elements have been developed to simulate steady and unsteady two-dimensional free surface flows. The depth-averaged velocity components with the free surface elevation have been used as independent variables in the model. The differences between the various elements presented lie in the choice of velocity approximation. The Newton-Raphson method has been used to solve the non-linear system of equations. Emphasis is put on bench-mark examples to assess the accuracy and efficiency of the elements. A simple stable new element tested herein shows promising advantages for industrial finite element codes.

A simple extrusion process for Newtonian and power-law fluids is analysed. Marker particles are introduced to analyse the fluid flow motions. Area co-ordinates of six-node triangular element are used to determine the marker position in the element. With this element, the solution algorithm becomes s
A new surface-capturing method is developed for numerically simulating viscous free surface flows in partially filled containers. The method is based on the idea that the flow of two immiscible fluids within a closed container is governed by the equations of motion for an incompressible, viscous, no
