CategoryProperties/Options/Descriptions

Options

Include All Excitation Frequencies: Options include Yes (default) and No. Selecting Yes includes all excitation frequencies in the sampling. The No option includes minimum and maximum excitation frequencies in addition to the frequency samplings for natural frequencies.

Include User Defined Frequencies: Options include Yes and No (default). Selecting Yes enables you to manually enter frequencies in the Tabular Data table (User Defined Frequency Steps).

Clustering Frequency Points: The default value is 20. This property defines the number of frequencies generated for both sides of the natural frequencies for response PSD result evaluations. If your response PSD curve contains a number of spikes, you can add more frequency points to obtain a more accurate RMS result, however; this increases evaluation time.
