I/O Options Entry

ROTATION - Output Request

Description

The ROTATION command can be used in the I/O Options or Subcase Information sections to request the output of rotation information for all subcases or individual subcases respectively.

Format

ROTATION (format, form) = option

Argument

Options

Description

format

<HM, H3D, OPTI,
PUNCH, OUTPUT2, PATRAN, APATRAN, blank>

Default = blank

HM:

Results are output in HyperMesh results format (.res file).

H3D:

Results are output in Hyper3D format (.h3d file).

OPTI:

Results are output in OptiStruct results format (.disp file).

PUNCH:

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

OUTPUT2:

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

PATRAN:

Results are output in Patran format (multiple files).

APATRAN:

Results are output in Alternative Patran format (multiple files).

blank:

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

 

form

<COMPLEX, REAL, IMAG, PHASE, BOTH>

Default = COMPLEX

COMPLEX, blank:

Provides a combined magnitude/phase form of complex output to the .res file if HM output format is chosen.  The REAL form of complex output is used for other formats, if they are not specifically defined.  (Phase output is in degrees).

REAL, IMAG:

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

PHASE:

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

BOTH:

Provides both polar and rectangular formats of complex output.

 

option

<YES, ALL,
NO, NONE, SID>

Default = ALL

YES, ALL, blank:

Rotations are output for all nodes.

NO, NONE:

Rotations are not output.

SID:

If a set ID is given, rotations are output only for nodes listed in that set.

Comments

1.When a ROTATION command is not present, rotations are not output.
2.The form argument is only applicable for frequency response analysis.  It is ignored for other analysis types.
3.The form BOTH does not apply to the .frf output files.  Results are output to these files using the rectangular form of complex output when BOTH is the chosen form.
4.Multiple formats are allowed on the same entry; these should be comma separated.  If a format is not specified, then this output control applies to all formats defined by OUTPUT or FORMAT commands for which the result is available. See Results Output 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.
