fatigue simulation

[SE-Bologna]

hi to everyone, I'm pressing that I have to coordinate a project but that I'm not exactly the engineer that typically deals with fem.
I ask you if you can give me information about a problem that maybe for many of you is already known.

I have to verify an aluminum die casting that must be mounted in a group and resist a max load of 200kg.
die-casting has a life cycle of 100k loads, but we can assume distributed as follows:
20% max load 200kg
30% load 150 kg
50% load 100 kg
with always variable load applications

so I ask you
1) Are there any fem tools that allow to vary the load in the fatigue calculation?
2) if I have fixed loads to be applied to the machine in physical testing, what load would you charge during all 100k cycles to have a reliable fatigue test?

Solidworks symulation in advanced version has the module for fatigue calculation and you can set the loads one after the other cumulative.
In my opinion, fatigue analysis is to be done according to regulations and therefore to build by hand with the norm the values of cycles using wholer. certainly let everything do to the program automatically is much faster.
