Get nodal deformed coordinates using Python

[simulation_engineer_2022]

Hi everyone!


I would like to postprocess some nodal sets using python in Abaqus and now I'm stumped on this one. What I need is to extract nodal coordinates for every selected set in deformed state for the last frame of selected step. It could be any sort of array to be processed or output in file, it doesn't matter.

What is the proper (and/or fast) way to do this? I've tried to record a macro for Probe Values function "Write to File" but it is not recorded. I could request COORD, but what's next? Should COORD be Field or History Output?

Making a "for" loops over all my sets and all nodal results in them seems to be too straightforward and too slow.

I would like to use python because number of sets is unknown and could be large enough. It would be great if you could point me to the specific Abaqus python methods required to accomplish this task.


Thanks in advance!

Check the documentation section Scripting --> Accessing an Output Database --> Using the Abaqus Scripting Interface to access an output database --> Reading from an output database. For loops are completely normal here.
