format

FORMAT - Output Control

The FORMAT command can be used in the I/O Options section to indicate the format in which results are to be output.

FORMAT = option

Argument	Options	Description
option	<ASCII, OS, OPTI, HM, HYPER, BOTH, H3D, FLX, NASTRAN, PUNCH, PATRAN, APATRAN, O2, OUT2, OUTPUT2, NONE>	OPTI, OS, ASCII:	OptiStruct ASCII results files are output.
	Default = FLX	HM, HYPER:	The HyperMesh binary results file (.res file) is output.
		BOTH:	Same as defining both HM and OPTI.
		H3D:	Hyper3d binary results file (.h3d file) and an HTML report (.html file) are output.
		FLX:	Same as defining both HM and H3D.
		NASTRAN, PUNCH:	The Nastran punch file format (.pch file) is output.
		PATRAN, APATRAN:	A number of Patran ASCII results files are output. APATRAN outputs the same files using an alternative file naming convention.
		O2, OUT2, OUTPUT2:	Nastran binary output2 file format (.op2 file) is output.
		NONE:	Analysis output is not required. Cannot be used in combination with other FORMAT commands.

Information provided on OUTPUT entries takes precedence over information provided on FORMAT entries. If neither of these entries are defined, the output formats defined in the OptiStruct Configuration File are used. If no format is defined by the configuration file, then both the HM and H3D formats are active by default.
Multiple FORMAT commands are allowed.
It is recommended to use the OUTPUT command instead of the FORMAT command since it is more flexible and allows different frequencies of output for different formats during an optimization.
