A finite volume technique has been introduced in an attempt to simulate a viscoelastic flow. The steady flow of a White–Metzner fluid through a 4:1 abrupt contraction has been chosen as a prototype example because of the existence of previous simulations in the literature. The finite volume method (FVM) is used to discretize the conservation and constitute equations with a Hybrid scheme with appropriate treatment of source terms. The FVM is proven to be quite capable of handling numerically viscoelastic models with low computational cost. Its use is recommended as a viable alternative to the solution of viscoelastic problems using a variety of constitutive models. Copyright © 2001 John Wiley & Sons, Ltd.
