Several ANSYS publications, particularly the Mechanical APDL Verification Manual, describe additional
spectrum analyses.
The Mechanical APDL Verification Manual consists of test case analyses demonstrating the analysis cap-
abilities of the program. While these test cases demonstrat e solutions to realistic analysis problems, the
Mechanical APDL Verification Manual does not present them as step-by-step examples with lengthy data
