Abaqus - Obtain Failure Index for Tsai-Wu Failure Criteria

Hi all,


I'm currently working on analysis of composite plate using Tsai-Wu Failure criteria.

I've modelled the composite plate with *FAIL STRESS option and value of f*.

Also I've selected *CFAILURE option in Field output.

My question is, How can we obtain the value of Plane Stress Failure Index (IF as specified in documentation)??

Thank you
