Hello,

I´m getting problems with dynamic viscosity. Even when i try to simulate a simple problem (2D) of a fluid flowing in a cylinder i got errors.
The same error for other problems. When I put dynamic viscosity iqual or higer than 1 Pa.s it works very well. However dynamic viscosity lower than 1 Pa.s i got a: "failed to find solution: maximum number of Newton iterations reached. Returned solution has not converged"
I believe that my boundary and subdomains conductions is right. For the 2D and 3D flowing fluids the inlet velocity is 0.01 to 0.1 m/s and outlet is 0 Pa.
