In Altair Hyperlife while selecting input subcase and input PSD in load map panel , two sets of excitations are automatically created ( Excitations 1& Excitation 2 ) Just wanted clarification on what they represent.

    Hello Harshit,

    While mapping the subcases automatically with the PSD, it will create AUTO PSD for subcases 6, 7  and 8 and CROSS PSDs for 6 and 7 respectively, CROSS PSDs will contain phase information.

    In case if you do not have that information, you can leave blank, it won't get calculated within the event.

    Regards,
