I/O Options Entry
PFPANEL – Output Request for Acoustic Panel Participation
Description
The PFPANEL command can be used in the I/O Options section to request output of acoustic panel participation factors for all Modal Frequency Response subcases.
Format
PFPANEL (PANEL=setp, FREQUENCY=setf, outfile,peakout) = setdof/PEAKOUT
Examples
PFPANEL(PANEL=ALL,FREQUENCY=45)=12
PFPANEL(H3D, PEAKOUT)=56
PFPANEL(H3D, PEAKOUT)=PEAKOUT
PFPANEL(PUNCH)=32
Argument |
Options |
Description |
|
setp |
<ALL, NONE> Default = NONE |
ALL: |
Output acoustic panel participation for all panels. |
NONE: |
Do not output acoustic panel participation. |
||
|
|||
setf |
<ALL, SID> Default = ALL |
ALL: |
Participation factors are processed for all excitation frequencies. |
SID: |
Participation factors are only processed for a set of excitation frequencies. SID refers to the ID of a SET of type FREQ. |
||
|
|||
outfile |
<PUNCH, H3D> Default = H3D |
Panel participation can be exported either into a H3D file or a PUNCH file. Because of the large volume of data, it is recommended to export the panel participation data into a H3D file. |
|
|
|||
PEAKOUT |
If PEAKOUT is present as an option inside the parentheses of the PFPANEL data, the filtered frequencies from the PEAKOUT data will be considered for output of panel participation. |
||
|
|||
setdof/ |
<SID/PEAKOUT> |
Degrees-of-freedom for which the panel participation factors are to be processed. SID refers to the ID of a SET of type GRID. If PEAKOUT is specified instead of SID, the output will be considered at the filtered frequencies corresponding to the degree-of-freedom in the PEAKOUT card in the bulk section. |
|
| 1. | Output is to the H3D or PUNCH files only. The output of both PFMODE and PFPANEL must be either to an H3D file or to a PUNCH file. Both PFPANEL and PFMODE must have the same output option. |
| 2. | Acoustic panel participation factors are available in a coupled frequency response analysis (Modal Frequency Response only). |
| 3. | The FREQUENCY keyword can be used to select a subset of excitation frequencies available. The closest loading frequency will be chosen in this case. |
| 4. | Legacy format for the export of acoustic panel participation to H3D or PUNCH files: PFPANEL (OUTPUT=outfile)=setdof/PEAKOUT is also supported. |
