摘要：In this work an improved moving lagrangian interface technique applied to update
the front position between two fluids is presented. The main drawback of classical lagrangian
schemes is the progressive distortion in the distribution of the markers used to identify the
material front. To avoid this problem a redefinition of markers obtained using a diffuse
approximation technique is proposed. The remeshing algorithm imbedded in the
computational fluid dynamics code is described. Aspects of the capabilities of the proposed
formulation are evaluated in a simple test: the filling of a step mould.
