Fan Segmentation dialog box

Operation Name
Sets the name of the fan segmentation.
Segment Definition
Maximum Computation Frequency	Sets the maximum computation frequency in Hz.
Sound Speed	Sets the speed of sound for the acoustic medium.
Maximum Segment Size	Displays the maximum fan blade segment size, which is computed using the formula:where: = Fan blade segment size (mm) = Speed of sound = Maximum computation frequency (Hz) = Number of segments per wavelength = 4Note: The computed segment size will be smaller than the acoustic wavelength and will be rounded down to the nearest millimeter.
Fan Rotation Axis (around Z from X to Y)
Specify CSYS	Lets you specify or modify the fan rotation axis coordinate system. A fan noise source rotates around the Z-axis of the specified axis system from X to Y (right-hand rule).For more information, see CSYS dialog box.
