I did time-series fatigue analysis and I saw some nodes are more than yield, then I did EN analysis. I obtained a good result. 

The only thing that confuses me is that when I do structural analysis of the same loads in the time-series, it comes out close to the yield strength. In time-series, it exceeds the yield strength. In fact, the difference in tension between the two is about 6%.

If I use time-step load provider, I have to change just the scale factor. However, there are many loads in datas. Actually, I did today, but the life was more then 1E8, and this is not true. Is there any method?
