摘要：

A numerical method is presented to analyse unsteady viscoelastic flow. Unsteady calculations may be used to find steady-state solutions as a limiting case. The solution scheme employs a mixed method with a decoupled Picard iteration solver. The elastic extra stress tensor is integrated with a space-time finite element method: the time discontinuous/streamline upwind Petrov-Galerkin (TD/SUPG) method. The Jeffreys, Phan-Thien/Tanner and Leonov models are used. The method is consistent, contrary to previously defined techniques.
