General Signal Processing - Surface Tab
The Surface tab is active when an H3D file or CASE file containing time domain flow pressure results are loaded into the utility.
- Input Signal Selection
- Display the transient animation of a pressure flow result for a specific time duration.
- Output Request
- Set the band type (Custom, Octave, or 1/3 Octave) and output frequency range. The upper limit of the frequency range can be up to 0.6 times the sampling frequency and the lower limit can be reciprocal - four times the time duration.
- Signal Processing Parameters
- Select and apply Block Size, Bandwidth, Overlap %, or Time Windowing, which are used to generate the dB Map.
- Result Generation
- Select Frequency Filtered Transient Animation or dBMap.
- Result Visualization
- Frequency-filtered transient animation or dBMap are loaded or set as an active window when the result file is selected from the drop-down menu. From the list box, select the frequency step for the results to display.
- Batch Run Support
- Generate the surface result in batch mode. Copy and modify the batch template file, Batch_Surface_Template.xml, which is located in hwdesktop\utility\nvh\fin\generalsignalprocessing.
