I am creating an Abaqus script to get image for max stress and strain of parts across each time increment.
Script should open odb files in Abaqus Viewer in no-GUI mode and find out in which time increment each part has max stress and strain, and get an image output of the same. For getting the max values I am using Report-> Field output option API [session.writeFieldReport()]

My script is working fine in GUI mode but not in Non-GUI. May be beacause I have used displayGroupOdbToolset library.
Can anyone please help me to modify the code so that it may work in non-GUI mode.

Following is my code to get max result values for each part.
