G'day

I have few questions have not found answer to them on the help manual

what is the fatigue damage direction results in NX Durability ---it is unit-less so it is not the direction. We can show the damage location and the life but it is so much useful if there is indication about the damage direction // I hope to find help in explaining what this factor means and if it is represent the direction of damage also why it is unitless

How to define block of loading say: 100 cyeles of 100Mpa amplitude followed by 200cylces of 250amplitude. I can see that we can define the cyclic loading using the pattern path but cannot find the repeating no. of cycles.

Thanks
