heal.abstract	Numerical simulations for the benchmark extrusion problem of an IUPAC-LDPE melt through capillary dies of infinite length have been performed using the finite element method with the u-v-p formulation. A modified version of the K-BKZ integral constitutive equation (the PSM model) has been used to model the viscoelastic stresses of the melt. Mesh refinement with five different meshes is carried	en
