How to extract acceleration from transient analysis by modal superposition Ansys APDL?

[cassio braganca]

Hi i'm doing transient analysis of a simple supported beam by Ansys and i can't extract the acceleration time history when i use the modal superposition, only the displacement. Through the Full method I was able to extract the acceleration as a function of time, I would like to know if it is possible to do the same thing by modal superposition.

Could you not differentiate the displacement, twice, wrt time, to get the acceleration?
