Use the NSORT and ESORT commands to sort the data before listing them.
Many other functions, such as mapping results on to a path, transforming results to different coordinate
systems, load case combinations, etc., are available in POST1; see Solution in the Basic Analysis Guide
for details.

4.5. Sample Harmonic Analysis (GUI Method)
In this sample problem, you will determine the harmonic response of a two-mass-spring system.
4.5.1. Problem Description
Determine the response amplitude (Xi) and phase angle (Φi) for each mass (mi) of the system shown
below when excited by a harmonic force (F 1 sin Ωt) acting on mass m 1.
4.5.2. Problem Specifications
Material properties for this problem are:
m 1 = m 2 = 0.5 lb-sec^2 /in
k 1 = k 2 = kc = 200 lb/in
Loading for this problem is:
F 1 = 200 lb
The spring lengths are arbitrarily selected and are used only to define the spring direction. Two master
degrees of freedom are selected at the masses in the spring direction. A frequency range from zero to
7.5 Hz with a solution at 7.5/30 = 0.25 Hz intervals is chosen to give an adequate response curve. POST26
is used to get an amplitude versus frequency display.
