Error: Divergence detected in AMG solver: uds-0

I'm trying to modify the k and e equations in the k-e turbulence model using user defined scalars.
I obtained this error "Error: Divergence detected in AMG solver: uds-0
Error Object: #f" when I modify the viscosity to a non-newtonian viscosity.
The viscosity expression is:
The residuals for the continuity increases until the simulation stops.
If I teste an expression for viscosity like that viscosity=0.2*ShearRate^(-0.4)
the solution converges.
Please someone can help me? It is very important for me solve this question and I don't have any ideia why it is happening
