I am trying to model concrete. I use Herschel-Bulkley as viscosity model. My calculation either gives an error or becomes instable, but only when I use tau0.
I have a 2D model of a pipe with a velocity on one side and a pressure on the other side.
I have found examples with Herrschel-Bulkley model but not in which tau0 is not 0. Which I find strange
Does anybody have a similar problem?
