Turn this option on if you want the small deflection or buckling analysis that you are setting up to output information about the dominant cause of warpage.
If you are setting up a small deflection analysis and turn this option on, you will receive four sets of deflection results representing the deflection of the part considering all factors, the deflections due to differential cooling, the deflections due to differential shrinkage and the deflections due to orientation effects.
If you are setting up a buckling analysis and turn this option on, the analysis log will include a sensitivity factor for each of the possible contributors to warpage: differential cooling, differential shrinkage and orientation effects.
