How to use Casson model in CFX -- CFD Online Discussion Forums

zhou Guest Posts: n/a	I have read the tutorial about non-Newtonian fluid flow, but it only refers power-law fluid. Actually, I want to use Casson model to compute blood flow in CFX. As I know, the casson fluid has no shear strain rate when the shear stress is lower than yield stress. At this time, the apparent viscosity is infinite. How can I express the infinite value in the expression of viscosity? Thanks all! I am looking forward the right way!
