Abstract
This paper deals with a numerical procedure concerning rheological parameters identification of viscoelastic constitutive models by using simulation codes within a loop of optimization. The generic model is a finite element simulation of viscoelastic fluid flows with differential constitutive equations. The inverse problem is solved by minimizing a cost function which measures the discrepency between experiment and simulation response. A simplex method is introduced which enables to use any simulation code without any modification.
