3D Nozzle meshing
 

Hi all,
I'm trying to simulate the flow for a 3D nozzle with a domain. I have validated the same nozzle for a 2D. But now I'm facing convergence issues in 3D. I would appreciate it if anybody can check my generated mesh. My epsilon and k residuals keep on increasing with fluent warning of "negative epsilon/K in X cells after linear solve".
I would like to thank everybody in advance if you have some suggestions for me.
