Schedule Random Vibration

I've been trying to setup a schedule to run the natural frequency (modal) followed by a series of test that all reference it, random vibration, frequency response, etc. Each one has it's own design scenario and I have made sure that both the surface and internal meshing is the same from one design scenario to the next; however, when I try to schedule the Random Vibration right after the Natural Frequency analysis, it runs two Natural Frequency analyses. Is there anyway to schedule dependant analyses one after the other?

Hi ServusJeff,

 

If I understand correctly, you schedule a modal analysis, and later schedule the random vibration analysis. What I am not clear about is what happens when the scheduled analyses run, but I think you are saying that it runs the modal analysis two times, and the random vibration analysis does not run at all. Is my understanding correct?

 

The obvious thing to check is that you are specifying the proper design scenarios when scheduling the analyses. In fact, you do not need to schedule each one separately. Just specify which design scenarios you want to run in the appropriate box, and it will run them sequentially.
