Hi

I compared the 2 links that you submitted and found that VM256 seems easier to apply.  The command CINT is used to get the value of J.In VM143, a userfile needs to be  created to define the equation to compute J.  

Are the 2 methods 2 different ways to obtain J, or a userfile is necessary, even if the method shown in VM256 is used?

The first one (https://www.sharcnet.ca/Software/Fluent14/help/ans_vm/Hlp_V_VM143.html) uses the displacement extrapolation method (KCALC command), and the second (https://www.sharcnet.ca/Software/Fluent14/help/ans_vm/Hlp_V_VM267.html) uses the J-Integral (CINT command) method. They are two different ways. A userfile is needed for VM143 only.
