So I understood that FT is a post-processing step and then the FE stresses are not affected by it.
What I mean when I said that the results changed is that when I'm change the load and I keep the same history data in the FT, at the end, the results of the FT change, I will have more or less elements in red colors depending of the load I used in the static analysis.
I don't understand why we have a link between both because as we said, the load I put in the static is just serves to calculate the behavior of the part in terms of stresses to be used in the FT.
FY = 20N / Mapping FT
FY = 50 N
So what I understand is that the fatigue tool will take account of the static structural analysis we did before.
I thought that we can use a random value for the force in the static analysis.
