The fatigue results are independent of actual time.  Consider a loading scenario that produces 2 result sets with fatigue damage caused by the stress difference between those sets.  It does not matter if the stresses occur .2 seconds apart or 1 second apart (or any other time difference).  The time between the result sets does not affect the calculated fatigue damage.

The static stress must be saved in a separate result set.  It does not matter if that result set is from a unique system or from the same system as the acceleration loading.  You could use 2 systems, or you could use 1 system with multiple result sets.  DesignLife translates all imported results sets into one results file.
