INTRODUCTION Implicit Finite Element techniques for solving three-dimensional free surface problems in complex geometries have recently been proposed by Legat and Marchal. Direct and Inverse Extrusion Problems have been addressed (ref. 1,2), and an original method is proposed to predict the shape of the die from a prescribed extrudate geometry. Power law as well as Newtonian fluids have been considered. Surface tension has been introduced in order to analyze its effect upon the extrudate shape for the Direct and Inverse Problems. In particular, the effect of surface tension upon the presence of corners is considered in (ref. 3). In this paper, we use the method presented in (r
