The highest design effort is caused by the extrusion die, which, at the current state of the art, has to be designed based on experience and running-in experiments. One of the key properties of plastics melts are their viscoelastic behavior, which leads to die swell when the material leaves the shape giving extrusion die. An important step towards dimensional accuracy is therefore the accurate numerical prediction of the amount of die swell. The latter will be your task. Towards this goal, a viscoelastic model will have to be analyzed regarding its numerical properties and subsequently implemented into the existing flow solver. Simulations will be based on an in-house software employing stabilized finite element formulation of incompressible flow.<\/p>\n<p style=\"text-align: justify;\"><strong><span style=\"color: #ff0000;\">The program will start as soon as possible for a duration of 5 years.
