Select a harmonic analysis case, select Analysis > Analysis Type and click Parameters, or click OK in the New Case dialog
to define the harmonic analysis parameters for each new dynamic case in a structure. It can also be called up by changing
the structure analysis type to harmonic analysis.
NoteTo define harmonic and harmonic in the frequency domain (FRF) analysis types, you need to define modal analysis first. Otherwise, these analysis types are not available.
Mass Matrix and Excitation harmonic analysis parameters may be selected for the load Case.
You can select the following mass matrix types:
- Consistent (complete matrix - always with regard to rotational degrees of freedom).
- Lumped with rotations (diagonal matrix - with regard to rotational degrees of freedom).
- Lumped without rotations (diagonal matrix without rotational degrees of freedom).
The Acceleration field and the standard buttons OK, Cancel and Help are located in the lower part of the dialog.
