POLYMAT - it may happen that POLYMAT ignores the weight of G' anf G" when fitting the parameters of a model.

User attempts to identify the material parameters for a non-isothermal single-mode Giesekus model, where the weight for linear properties (G' and G") is set to 10^-12. The fitting is poor, and seems to ignore the selected weight. It should be checked whether the data (G', G", viscosity) are provided with increasing abcissas (respectively frequency, shear rate). |
