      Good evening all !!


      I m trying to work vortex tube in fluent, i tried to keep mesh skewness less than 0.8 and number of iterations is at 100. while run calculation i m getting "floating point exception". i have attached some pictures of the analysis. 


      Open to all your advice.

      All discretization schemes to first order. User PRESTO! for pressure interpolation. Use coulped solver with option pseudo-transient. Ensure that skewness, ortho quality, aspect ratio and cell volume change are of good range.

      Check your inlet: why it does depict very small velocities. You do not require to provide gauge pressure at your velocity inlet as your flow will remain subsonic.

      Thanks for your valuable suggestions, i m really new to ansys and i will try my best. Hope i can solve this problem very soon.
