Reply To: Plasticity: Extract nodal solution from specific steps, substep

Thanks Debanjan for the recommendations. I have been practicing the examples from the ANSYS ACT Customization Guide for Mechanical (2019 R3). Particularly the code from 2.3.1.2. Defining Functions for the Custom Result (Von Mises Stress) has been very useful. I am interested in using "PRIN_S" option. While trying to validate the script results at a single corner node, I see some scatter in the results when compared to those given by user-defined results (S1,S2,S3). Mostly the differences are in the middle and minimum pricipal stresses. Later I found that the script results match the 'Average' data when 'Unaveraged' display option is chosen. 

I am not able to understand the scatter between the data with Averaged and Unaveraged (min+max/2) results. Please inform if I have missed anything and inform about methods to achieve the same results as the Averaged data from ANSYS. 

Additionally, I also interested in the middle nodes. But the PDF available online is missing some part of the code for defining the link table that provides the two corner nodes. Please let me know where this can be found.

Thanks for your support.
