Extract results from a region of interest Abaqus

[jj31]

Hello,

I have an Abaqus 3D model of quadratic tetrahedral elements (10 nodes). I would like to make a series of 4 planes or cuts. Then, I would like to define a 2D region of interest (say for simplicity a square) on each plane and extract the results (i.e., stress, strain, etc) from inside the specific region of interest. Can anyone point me in the right direction on how to do this (i.e., extract information from a 2-D region of interest in a 3-D model) using a script?

Thanks,

J

I think you need to identify the nodes on your region of interest and you can use this code to extract data
session.xyDataListFromField(odb=odb, outputPosition=NODAL, variable=(('S', INTEGRATION_POINT, ((INVARIANT, 'Max. Principal'), )), ), nodeLabels=(('Part-1-1', ('5', '10', '11', '21', )), ))
5, 10, 11, and 21 are node numbers

If your nodes are in a set you can use
session.xyDataListFromField(odb=odb, outputPosition=NODAL, variable=(('S', INTEGRATION_POINT, ((INVARIANT, 'Max. Principal'), )), ), nodeSets=("Node_set-1", ))

Another option is to use integration point of each element at your region of interest.

session.xyDataListFromField(odb=odb, outputPosition=INTEGRATION_POINT, variable=(('S', INTEGRATION_POINT, ((INVARIANT, 'Max. Principal'), )),), elementLabels=(('Part-1-1', ('1', '2', '3', )), ))

'1', '2', '3' are the element numbers

Hi @GreenElmo,

If I understood correctly, your code will only extract the data at those 4 nodes. But what I need is a little bit different, I need to get the data from everything that is inside the area defined by those 4 nodes.

Your nodes must be your upper and lower boundaries. Anything in between those nodes will be within the node boundaries. You may try to interpolate.
