This task allowed us to make a first step in non-newtonian liquids studies and to visualize the behaviour of a viscoelastic fluid ruled by the Phan Tien - Tanner model. We could see influences of parameters such as the Deborah number. But it is difficult to analyse results without well knowning the physics of this phenomena. This task was a very interresting initiation.

The use of the preprocessing polydata is quite easy. We can note that it is necessary to unlock the Numlock key on the keyboard or the software will not run correctly. Morover the user must be aware of working with an increased swap zone on his working platform.
