For an FFT specialized for time history simulation, the number of multiplications at
each discrete time is in the order of y , in which the total time points Nt=2' (
Heideman and Burrus, 1986). Some new FFT algorithms can be even faster (
such as ...

The question is therefore; can a combined use of time and frequency domain
analyses give the same information as the complete time domain simulations, but
with significantly less effort? CHOICE OF RESPONSE FOR STUDY From the ...

Figures 5b, 6b, and 7b present the KBLDYN simulation heave displacement,
velocity, and acceleration autospectra, respectively. The results obtained from the
simulation of DDIOH72 indicate that for the heave degree of freedom, KBLDYN ...
