Fluid not flowing through nozzle

I have modeled an electrolyte within a nozzle surrounded by air. I have also modeled a separate electrolyte domain (a meniscus) at the outlet of the nozzle. The meniscus was drawn on a work plane and then revolved to make a 3D part, Basically, the fluid should diffuse at the meniscus / air interface and generate a convective flux within the electrolyte.
I have defined all the necessary boundary conditions for laminar flow / transport of diluted species. However, the fluid is not flowing as when I plot the velocity it is zero throughout the nozzle.
What could the issue be? This is a 3D model by the way. I have modeled the same system in 2D and 2D axisymmetric and obtain accurare results.
