  Hi,
  I want to vibration analysis in nCode DesignLife, however there is a problem about the load.
  I fixed the holes and there is no any load on the model. I have Hz-g^2/Hz datas and I added the histogram input.
  Although I try to do this analysis many times, I always encounter this error. How can I solve this problem? Is my analysis wrong or not? Can you help me, please?

  The integrated Ansys nCode DesignLife system is designed to use harmonic rresults. You can use either a full harmonic analysis or a mode-supe harmonic analysis.

    Today, I analyzed Harmonic Analysis (X,Y and Z direction). However, when I calculate the life result, there is no any life result in nCode DesignLife. I have acceleration-time datas from accelerometer and I calculated FTT and PSD datas for all directions.
    Firstly, Should I use general acceleration or acceleration values from accelerometer as (tabular) data in Harmonic Analysis?
    
    Secondly, my worklow is like this photo. Is it true?
    
    - What should I use loading type in edit load map? (vibration-duty cycle) I tried to do as matrix but I couldn't do. There are 3 available FRF Load Cases, I cannot add 3 FRF loads, so there is no life or damage in the model.
