J-Integral scripting

[arya1996]

Hi at all
I am trying to calculate j-integral for 5 contours by abaqus script, and although I have tried to find in user manual of abaqus, I didn't find anything useful.
I know its as simple as writing one line of code, but I don't know what to write.
Can anyone help me with a line of code?

 

[FEA way]

J-integral is available as history output so check the documentation chapter "Reading from an output database" in Abaqus Scripting User's Guide.

I don't know why the code below does not work !

Jint= odb.steps['Step-1'].historyRegions['Assembly ASSEMBLY'].historyOutputs['J-Integral'].data

I have determined 5 contours for my J-Integral
how do I fine the code??
