These are available under "Resid In" and "Resid out" parameters.

When you look at the convergence plots, at the right hand side you have tabs labeled Global, All, Avg etc. Click on Avg, you will have then the option to view "Resid In" and "Resid Out".

Hi OJ

 

Can see this plot and when I save it is not any value of "Resid Out" ?

 

Can you explain me more precise how to catch "Resid Out " value ?

Just wanted to make you aware there is a fairly detailed discussion about these quantities in the help:

http://wikihelp.autodesk.com/Simulation_CFD/enu/2013/Help/0030-User_Int30/0066-Output_B66/0067-Conve...

If you want to see the actual values instead of the trend look at the table tab instead of plot.

The resid out value per se may not be too useful since it is not normalised one (like other CFD codes, eg FLUENT, CFX etc). Rather, the ratio of resid in and resid out provides more insight into convergence. 

 

Have a look at following thread where it is discussed.
