how to get acceleration after Ansys harmonic analysis run

how to get acceleration after Ansys harmonic analysis run

(OP)
after running the harmonic analysis in Ansys, the output is usually displacement against frequency, how can I get acceleration against frequency? Thanks

RE: how to get acceleration after Ansys harmonic analysis run

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.

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.
