FREQ command does not allow enough data points
FREQ command does not allow enough data points
(OP)
I am working on a spectrum analysis for a water tower in order to see how it would respond to an earthquake.
I've managed to get the earthquake data in terms of frequencies and acceleration responses but I have about 2000 data pairs I would like to input.
I'm ready to fill out the FREQ and SV values but it only allows a maximum of 20 points.
Is there any way I can get all 2000 in there?

if you have a time-history, then you'd better perform a transient analysis; if you have spectra, then you'd better perform a spectrum response analysis. If you deal with spectra, generally it is easy to "simplify" the spectra to fit into a 20-points table. At least, this is what I've done several times with the italian accel spectra.
