Abaqus - Calculating Failure Index of Composites in Abaqus

Anyone, who has done a composite analysis in Abaqus?

I have calculated Tsai hill, Tsai wu stresses but I want to calculate Failure Index IF ( as I have already input strengths in material>suboptions>fail stress, I am interested in failure). Is the stress calculated as Tsai wu, tsai hill in attached image same as Failure index? Please
