Response spectrum analysis in ANSYS 1

[Daniel paul]

can any tell that, how to find out response spectrum analysis in ansys...
when we give time domain as the input signal, and how to get frequency domain signal.

Coutesy the vendor:
"When trying to interpret time-sequence data from a transient solution, it is often useful to look at the data's spectral (frequency) attributes. For instance, you may wish to determine the major vortex-shedding frequency from the time-history of the drag force on a body recorded during a ANSYS FLUENT simulation. Or, you may want to compute the spectral distribution of static pressure data recorded at a particular location on a body surface. Similarly, you may need to compute the spectral distribution of turbulent kinetic energy using data for fluctuating velocity components. To interpret some of these time dependent data, you need to perform Fourier transform analysis. In essence, the Fourier transform enables you to take any time dependent data and resolve it into an equivalent summation of sine and cosine waves."
