In time history analysis, the magnitude of the applided load is determined by the product of the profile force, the force sets magnitude and the scale in the shock case.

The following are the cases we considere and i request you to suggest which one we shall follow,

Case-1, Profile force - 80 KN, Force Set magnitude 80 KN and the scale factor is 1, so the magnitude is (80*80*1).

Case-2, Profile force - 80 KN, Force Set magnitude 1KN and the scale factor is 1, so the magnitude is (80*1*1).

Case-3 Profile force is 1 KN , Force set magnitued is 80 kN ,and the scale factor is 1 (1*80*1)

Case-4 Profile force is 1 KN , Force set magnitued is 1 kN ,and the scale factor is 80 (1*1*80)

as it can be understood from the help file of CAESAR II
Case 2, Case 3 and Case 4 shall give almost the same results, but , surprisely we tried the technoiques in one of the models , and the results were totally different .
Please advise which one is the optimum.
