Convergence criteria/Analyzing Residuals
 

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
