Argument

Options

Description

format

<PUNCH, OUTPUT2, blank>

PUNCH:

Results are output in Nastran punch results format (.pch file).

Default = blank

OUTPUT2:

Results are output in Nastran output2 format (.op2 file).
 

blank:

Results are output in all active formats for which the result is available.

 

form

<REAL, IMAG,
PHASE>

REAL, IMAG:

Provides rectangular format (real and imaginary) of complex output.

Default =
REAL

PHASE:

Provides polar format (magnitude and phase) of complex output.  Phase output is in degrees.

YES, ALL, blank:

Comments

  1. When the SDISPLACEMENT command is not present, modal participation displacements are not output.

  2. The SDISPLACEMENT command is only valid for modal frequency response and modal transient solution sequences.

  3. The OFREQUENCY and OTIME I/O options may be used to control the amount of output.

  4. Multiple formats are allowed on the same entry; these should be comma separated. If no format is specified, then this output control applies to all formats defined by OUTPUT or FORMAT commands for which the result is available. See Results Output by OptiStruct for information on which results are available in which formats.

  5. Multiple instances of this card are allowed; if instances are conflicting, the last instance dominates.

  6. For optimization, the frequency of output to a given format is controlled by the I/O option OUTPUT. In previous version of OptiStruct, a combination of the I/O options FORMAT and RESULTS were used; this method is still supported, but not recommended as it does not allow different frequencies for different formats.
