vedravi New Member raviteja Join Date: Mar 2010 Posts: 9 Rep Power: 16	Hi, -Can you please explain me how exactly residuals/convergence/iterations/XY-PLOT works. Actually I have searched for the same online and could only get the following information setting 10E-03 for non-energy analysis and 10E-06 for other case. -But what exactly does these values signify. And also I am unable to get the concept of iterations, residual plots that show continuity, x, y, z where I get the X-Y plot having multiple values (y) for one point (x). Please help me with this as this is the main thing I am on hault at Fluent. Also I would be glad if tutorials on this area are suggested. Thank you -Ravi Last edited by vedravi; April 1, 2010 at 21:57.
