According to me, "through the apparent viscosity" is the easiest (but definitively efficient) way to account this kind of constitutive equation in non-newtonian flows. I am using a regularization law too in order to make the constitutive equation continuous (an exponential model from Papanastasiou). Thus, you can calculate the stress (or the apparent viscosity) even in zones where the stresses are smaller then the yield stress (that is to say where the shear strain is close to zero). It gives very satisfactory results!! Anthony

Dear
i need to your impelimentation, i want to simulate creeping flow aroound cylinder.
Thanks
