Forcing Frequencies dialog box (Ray Acoustics)

This modeling object lets you specify forcing frequencies for a frequency response analysis.

Modeling Object
Name	Defines the modeling object name.
Label	Specifies a unique numerical identifier for the modeling object.
Properties
Description	Lets you enter a brief description. Click to open a text editor where you can enter a longer description.
Frequency List
Frequency List Form	Specifies the form to use in frequency response solutions.
Frequency List	Appears when Frequency List Form is set to Individual Frequencies.Specifies the frequency unit. Hz is the default.
Frequency List box	Appears when Frequency List Form is set to Individual Frequencies.Lets you specify as many frequencies as you need.Enter the frequencies to include. Separate them by commas or spaces.You can also Cut, Copy, and Paste the frequencies.
Linear Sweep Defined by	Appears when Frequency List Form is set to Linear Sweep.Specifies the frequency range.Step ValueLets you set values for Start Frequency, End Frequency After, and Step Value.Note: When the End Frequency After value does not fit into the sweep definition, the software includes the next valid frequency in the frequency list. For example, if Start Frequency is 100,End Frequency After is 200, and Step Value is 75, the software exports 100, 175, and the next valid frequency, which is 250.When the End Frequency After value is greater than Start Frequency, the software generates one interval.Number of StepsLets you set values for First Frequency, Step Value, and Number of Steps.
Logarithmic Sweep Defined by	Appears when Frequency List Form is set to Logarithmic Sweep.Specifies the frequency range.BaseLets you set values for Start Frequency, End Frequency After, and Base of Logarithm.Note: When the End Frequency After value does not fit into the sweep definition, the software includes the next valid frequency in the frequency list. For example, if Start Frequency is 100,End Frequency After is 200, and Base of Logarithm is 75, the software exports 100, 175, and the next valid frequency, which is 250.When the End Frequency After value is greater than Start Frequency, the software generates one interval.IntervalLets you set values for First Frequency, Last Frequency, and Number of Logarithmic Intervals.
Lower Center Frequency	Appears when Frequency List Form is set to Octave, 1/3 Octave, or 1/12 Octave.Lets you enter the lower center frequency value of the frequency range.
Upper Center Frequency	Appears when Frequency List Form is set to Octave, 1/3 Octave, or 1/12 Octave.Lets you enter the upper center frequency value of the frequency range.
Limit Frequency Range	Appears when Frequency List Form is set to Use Frequencies from All Loads.Enter values in the From and To boxes to limit the range of the forcing frequencies.
