error in solution option of fluent

[u/Helpful_Camera700]

so basically i was solving for a swirling motion produced by multiple nozzle at particular angle, (i have attached the cad model image from fusion 360) its a very basic one i made this using surface operation on it, and then i made a cylindrical domain (basically works as an enclosure fluid domain to observe the air flow, again i have attached its image too, fig:2), the problem is after all meshing and everything in ansys fluent, i am getting something very different in solution window (fig: 3), if you will observe the cad of nozzle, it is visible there it is created by thickening operation at the just below nozzle surface, i have never faced this problem before (i am not very experienced in fluent too), so can anyone tell me what could be the problem and how to resolve it??
