I am trying to read J integrals and K Factors from an Abaqus history output database, but I'm however getting a KeyError for 'setname=_PickedSet24' which is the nodeset generated from abaqus cae for the cracktip node. The problem is symetric CCT model using abaqus V6.8.2.  In addition, as the script aborts at this point, I'm not quite sure how it will respond to variables 'J' or 'K' for J-integral and stress intensity factors respectively.

I am quite new to script writing and hope someone could share their expertise. Find my attempt below.

Hope the information provided surfices? Many thanks.
