Greetings
2D modeling from nozzle is fine and I can see a reasonable prediction for given mesh size and time step. There is a problem when I try to model 3D. Mesh size is 0.1 mm and time step is 0.00005. They are small enough. 
Look at following picture. This is the picture after 4500 time steps and inlet velocity 0.15 m/s.
