The only dynamic option for this type of analysis is the operating frequency range (in Hertz) of the harmonic loads. To specify the frequency range, use one of the following:

You have two general options: the number of harmonic solutions and whether to use stepped or ramped loads.

You can request any number of solutions. The program spaces the solutions (or substeps) even within the specified frequency range. For example, if you specify 10 solutions in the range 50 to 60 Hz, the program calculates the response at 51, 52, 53, ..., 59, and 60 Hz. Mechanical APDL calculates no response at the lower end of the frequency range.

By default, loads are ramped; that is, the load value increases gradually with each substep. By stepping the loads, you can maintain the same load values for all substeps in the frequency range. To specify stepped or ramped loads, use either method shown below:

The third class of load step options enables you to control output. The options are controlling printed output, controlling database and results file output, and extrapolating results. For information about output controls, see Using the Alternative Solution Option for 2D Static Magnetic Analysis.
