How does this look like? It must be a boundary, at least a single line!? Or do you want to model a source in the fluid??

Thanks for the help. I have a tobe contains a series of Nozzles (300) with very small diameters (0.0013 in) that spray a gas insilde a vacuum chamber. The gas in coming through a tube to the Nozzle tube. Since it is impossible to model the actual geometry of the nozzle. I tried to model it as an inlet (face) that is totally inside the region. I guess this definition does not constitute a mass source. Please Help me with any suggestion. Regards
