Neper -V postprocessing: how to get stress-strain values

[zengyan0112]

Hi,
I was tring to anlyze the relationship beteween the stress and strain, and I want to know how to get the stress- strain values.

Assuming you are using the -S module and the elemental stresses and strains are contained in your simulation directory, you can get the macroscopic values using -resmesh stress,strain. This will create a file for each step under the results/mesh/stress and results/mesh/strain directories.

Thank you very much !
In addition， I want to konw how to get the stress-strain curveof a specific node?

The stress and strain are defined at elements, not nodes. For elements, simply use the values in results/elts.
Please refer to the doc: https://neper.info/doc/fileformat.html#simulation-directory-sim.
