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.

Thanks in advanceBasic model Details of mesh 1Details of mesh (2)Solution methods detailssolution initializationRun calculation

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.
