As said in a previous reply, the nodes displaced in negative directional component.
586 9.07577E-03-4.36800E-02 1.37167E+00 0.00000E+00 0.00000E+00 0.00000E+00
The above node for instance has a negative Y displacement.

Hi sir,
it is the output of acceleration when i gave psd as input. ouput of psd can't be negative . if we give acceleration as output will it give in terms of g or g/Hz?
