SACCELERATION
I/O Options and Subcase Information Entry The SACCELERATION command can be used in the I/O Options or Subcase Information sections to request the form and type of modal participation accelerations output for all subcases or individual subcases, respectively.
Format
SACCELERATION (sorting,format_list,form,peakoutput) = option
Definitions
Argument | Options | Description |
---|---|---|
sorting | <SORT1, SORT2> | This argument only applies to the PUNCH format (.pch file) or the OUTPUT2 format (.op2 file) output for normal modes,
frequency response, and transient subcases. It will be ignored
without warning if used elsewhere.
|
format | <H3D, PUNCH, OP2, PLOT, blank> |
|
form | <REAL,
IMAG, PHASE> Default = REAL |
|
peakoutput | PEAKOUT Default = blank |
If PEAKOUT is present, only the filtered frequencies from the PEAKOUT card will be considered for this output. |
option | <YES, ALL,
NO, NONE> Default = ALL |
|
Comments
- When the SACCELERATION command is not present, modal participation accelerations are not output.
- The SACCELERATION command is only valid for modal frequency response and modal transient solution sequences.
- The OFREQUENCY and OTIME I/O Options may be used to control the amount of output.
- Multiple formats are allowed on the same entry; these should be comma separated. If a format is not specified, this output control applies to all formats defined by the OUTPUT command, for which the result is available.
- Multiple instances of this card are allowed. If instances are conflicting, the last instance dominates.
- For optimization, the frequency of output to a given format is controlled by the I/O option OUTPUT.
- In general, HyperView does not recognize the SORT2 format for results from the .op2 file. When results are output only in SORT2 format (<Result Keyword> (SORT2, OUTPUT2, ...)), the results are written by OptiStruct into the .op2 file in SORT2 format, but when the .op2 file is imported into HyperView, the results in SORT2 format are not recognized. Therefore, the SORT1 option is recommended for results output in OUTPUT2 format and SORT2 option is recommended for results output in PUNCH format.
- The abbreviations SACCE and SACCEL are interchangeable with SACCELERATION.
- format=OUTPUT2 can also be used to request results to be output in the Nastran output2 format (.op2 file).
