But it might also be worth checking as I have seen a presentation where the solvent viscosity was not mentionned on...

It is definetely possible to use a Generalised Newtonian with some Giesekus mode within RheoChart, but it might not be really necessary to include the purely viscous component. How many viscoelastic...

If you don't have data, you have to make some assumptions and that's propably a reasonnable one if your flow is dominated by shear effects....
