J-Integral to calculate for SIFS or not?

      Hello

      I am using the fracture tool and I want to calculate the Stress Intensity Factors of a semi-elliptical crack.
      In the Analysis setup i can choos, if I want to calculate the J-Integral or not.
      What is the difference for the solution of the SIFS, if I calculate the J-Integral also or not:

      Because I got different reluts for J-Integral "yes" and "no".

      Thank you for your time and work.

      Best regards,

      Elena

      Calculating the J-integral should not affect the SIFs calculation.  Please ensure that all other settings are consistent.
