TableD1 - frequency/Transient analysis
Altair EmployeeFor TableD1 units,
TableD1 used in transient analysis, the units are as follows:
x axis - seconds (s)
y - axis - acceleration (mm/s)
TableD1 used in frequency analysis, the units are as follows:
x - axis - Frequency (Hz)
y - axis - Magnitude (dB)
is this correct?

Altair EmployeeDoes SPCD also define excitation?
Altair Employeedoes SPCD (if used for acceleration) define excitation as well?

Yes,
In TABLED1 card for FRF analysis X defines frequencies and Y defines the excitation.
Provide consistent units.Hm optistruct is unitless.
See below post for reference.
