What is the stress obtained by position=ELEMENT_NODAL in odb?

What is the stress obtained by position=ELEMENT_NODAL in odb?

What is the stress obtained by position=ELEMENT_NODAL in odb?

(OP)
Dear all,

I have a quick question:

import odbAccess
odb = odbAccess.openOdb(odbFilePath)
frame = odb.steps[stepName].frames[frameCounter]
frame.fieldOutputs['S'].getSubset(position=ELEMENT_NODAL, region=myNode)


What is the stress obtained by this command? Specifically,
1) Is this averaged or unaveraged stress at nodes?
2) If this is unaveraged, what is this value? Since the node may belong to multiple elements, shouldn't it be multiple values instead of a single value?
3) If this value is averaged, where can I set the averaging threshold? (Note: this is not in the CAE)


Thanks!

-Shawn
