Ansys Polymat is an interactive graphical program that allows you to visualize material data, including steady shear viscosity and steady elongational viscosity. Ansys Polymat computes material properties from constitutive equations and numerical parameters, for isothermal and non-isothermal generalized Newtonian, differential viscoelastic, and integral viscoelastic fluids. It can also compare them with experimental curves (that is, fitting). The inputs for the model selection and parameters are similar to those in Ansys Polydata.
Figure 1.1: Fitting to Experimental Data shows an example of fitting. The shear viscosity and shear stress for a KBKZ fluid with 6 relaxation modes and a Wagner damping function are plotted
