BLF Convergence
The convergence index is the maximum percentage change of any BLF (buckling load factor).
In a buckling analysis, Creo Simulate calculates BLF and mode shape for each buckling mode you specify. The BLF is the magnification factor by which the loads applied in a previously specified static analysis would have to be multiplied to produce the critical buckling load.
