The geometry was the 4:1 plane contraction. *** This is only an illustrative case for the PP constitutive model. Therefore, there are not more details published until now for this model using this geometry and viscoelasticFluidFoam solver. *** The parameters for the constitutive model was obtained from: VERBEETEN,W. M. H.; PETERS, G.W. M.; BAAIJENS, F. P. T. Differential constitutive equations for polymer melts: The extended pom-pom model. Journal of Rheology, SOR, v. 45, n. 4, p. 823-843, 2001.
