UGNX Durability Analysis Question

Greetings,

I am setting up a durability analysis within the advanced simulations module based on a linear static analysis of several events. It is on an aluminum cast part for suspension.

I set up a durability solution with one static event and add three excitations based on three sub-cases results in the linear static solution. The durability requirement calls for the three event sequences to be evaluated at 600000 cycles.

Question 1:
Under the fatigue tab do I leave the number of occurrences at 1 and evaluate the fatigue life results to see if the lowest cycle is above 600000 cycles
or
Under the fatigue tab do I input 600000 occurrences and evaluate the fatigue life to see if the lowest cycle is above 600000 cycles or do I evaluate the plotting grid at some other fatigue life because I used the 600K for the number of occurrences.

Question 2:
Am I even setting up the simulation correct. Instead of one durability solution and one static event and three excitations should I be doing one durability solution and three static events with one excitation be static event? If I did it this way I could have more control over each event that rolls up into the solution.

Question 1 still pertains to Question 2.

Thanks ahead of time for any input.
