Frecuency domain Graph

Altair Forum User

Hi all!

 

Someone knows how to transform an acceleration graph in the time domain into Acceleration (RMS) in frecuency domain using HyperGraph?

 

Thank you!

a. Read the time domain data in the HyperGraph
b. Create a window in the PAGE-LAYOUT panel (two windows page-layout)
c. In the DEFINE-CURVE panel ADD a curve. Change the SOURCE to MATH
function

For X : freq(x-vector) (x-vector can be chosen by pressing SHIFT-button
and picking the time-domain-curve)
Y : FFTmag(y-vector) (y-vector can be chosen by pressing SHIFT-button
and picking the time-doman-curve)
