In the output of abaqus, why there are more than one stress values at the same time?
Thank you so much.

stress gradients
This nuisance can be caused by
1) large stress differences between integration points within an element (high stress gradient). I recall being confronted with this problem even though my Python scripts usually pick specifically the results for a specific component of the stress tensor at a precisely defined integration point (and not any average value over the element or a non-specific value like Mises stress or the like).
2) possibly also if you have your data written to files using a Python script and loop over several output databases. I had to observe that Abaqus tends to screw up data between different simulations (i.e., provides the data from the first simulation also for the ones to be evaluated subsequently).
