Obtaining stress at a particular x,y,z

Abaqus Users mailing list
i understand that when we extract stresees using python , we obtain the stress values at the integration points by default.

I use the following
lastframe.fieldOutputs['S']

is there a way I can obtain the stress at a particular x,y,z ( not an integration point or a node) ?

i understand that i can use GUI to do the path operation but I work with supercomputers and my files are so huge that I cant load it into GUI. I wouls like to use python to extract that .. please help!

Extract data along a short path that contains the point you’re interested in.

You can obtain the history output at a specific point if you want. Execute the following in Python:
 

 steps[name].historyRegions[name].getSubset(variableName='Sij').historyOutputs[name].data
 

 where i,j in Sij are the axes of the desired stress output.
 If you are familiar with Matlab, then you may be interested in Abaqus2Matlab, a new toolbox which enables direct post-processing of Abaqus results into Matlab, without the need to use Python. See  Abaqus2Matlab http://www.abaqus2matlab.com for more details.
 

 Best regards,

Yes, of course.  Record a macro while defining a path variable interactively, then edit the code as necessary.
