DENSITY - Output Request
The DENSITY command can be used in the I/O Options section to request density output for a topology optimization.
DENSITY (format,type) = option

format |
<HM, H3D, OPTI, PUNCH, OUTPUT2, blank> |
HM: |
Results are output in HyperMesh results format (.res file). |
| Default = blank |
H3D: |
Results are output in Hyper3D format (.h3d file). |
|
|
OPTI: |
Results are output in OptiStruct results format (.dens file). |

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

|
OUTPUT2: |
Results are output in Nastran output2 format (.op2 file). |
||
|
blank: |
Results are output in all active formats for which the result is available. |

|
|

|
type |
<ALL, DES> |
ALL: |
Results are output in all simulations. |
| Default = DES |
DES, blank: |
Results are only output in the design history simulations. |
|

option |
<YES, ALL, NO, NONE> |
YES, ALL, blank: |
Results are output |
| Default = YES |
NO, NONE: |
Results are not output. |

When the DENSITY command is not present, density results are output.
Density results are only available for topology optimizations.
Outputting the density results in all simulations allows analysis results to be plotted on the density iso-surface in HyperView.
The frequency of this output is controlled by the DESIGN keyword on an OUTPUT definition or, if no OUTPUT definition exists with the DESIGN keyword, by the DENSRES I/O option.
Only formats that have been activated by an OUTPUT or FORMAT command are valid for use on this card.
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.
Multiple instances of this card are allowed; if instances are conflicting, the last instance dominates.
