I am working on a number of mode based transient analyses and request acceleration and other history output to the odb. I can plot the acceleration vs time in ABAQUS/Viewer. If  I need to perform a quick FFT or simple statistics on these displayed data, it is not easy. Right now, I am exporting the ABAQUS output to a 3rd party software and performing the necessary operations. Is there a DSP tool available for ABAQUS/Viewer? or Is there a workaround for this process?

Thanks,

Bala.
