This is a question that I saw in Jul 2005. To my knowledge this can be done as follows:

(1) POSDAT has the vairable RESOR passed into it by default (2) RESOR (IV,IMAT) is the residual of variable IV in material IMAT. IV is the variable number like U=1, V=2 etc. Refer to nom.inc for the details (3) Write an IF stmt in POSDAT using LEVEL Eq 2. I think the program visits POSDAT once before and after iteration even after convergence. Else use level 1 (4) The IF stmt must have max(RESOR) to be verified with the set tolerance SETTOL. if max(RESOR) <SETTOL it means, the convergence criterion is attained and iteration is about to stop. (5) Write the values using POSDAT.

Hope this helps.

Thank you very much for your help. It works in way you described.

Glad to be of help. I was investigating this myself to write from POSDAT after convergence for some problem. Thought I could share. Good luck.
