The hydrodynamics
can be strongly affected by non newtonian characteristics such as viscoplasticity.
Since industrial fluids are always non-newtonian, it is very imporatnt
to be able to simulate and to resolve Navier-stokes equations with a non-constant
viscosity.

The aim of
this task is the modelling of a couette flow of a viscoplastic fluid with
StarCd.

The simulation
was perfomed with a 3D grid because StarCd is unable to use 2D grid. The
heigh of the cylinder is 0.1 m, Ri is equal to 0.6 m and R to 1m.
