simple harmonic motion, ie velocity = j*w*x, acceleration is -w*w*x
w is the angular velocity, ie 2*pi*f. j is sqrt (-1). x is the displacement at a frequency. Cheers

look at the math operations icon in the time history postprocessor there u have options like add, subtract, multiply, derivate, integrate etc.
first describe the displacement by a variable and then follow the instructions given by Greg to get velocity and again to get the acceleration.
