Keywords and Descriptions

Table 1.
Keyword	Description	Defaults
$DELIMITER	Specifies the delimiter (<SPACE> <TAB>, ; : . and so on) between the data. Note: # and $ should not be used.	<SPACE>
$TITLE	Specifies the title for analysis. It is an optional keyword.
$SUBCASE	Specifies the subcase ID and label.	ID = 1 Label = “Subcase 1”
$BINDING	Specifies result binding (NODE or ELEMENT).	ELEMENT
$LAYER_INFO	Specifies layer information (like the number of layers and layer labels).
$ID_POOL	Specifies the ID pool name. The possible values depend on the model file being read (typical values are: “Shell”,”Solid”,”Beam”, and so on). Note: If ID_POOL is given; then the ID pool name should match the model file ID pool names.	"Nodes" (for nodal bind result types) OR Elements (for element bind result types)
$SYS_ID	Specifies the output result system (like Ply (-3), Material (-2), Element (-1), Global (0), User defined). The material and ply system information should be available from the model file (currently supported for OptiStruct and Nastran only). Otherwise the results are displayed as N/A anytime coordinate transformation is performed, as HyperView does not have complete information.	0
$COLUMN_INFO	Specifies the meaning of data column (like entity ID (ENTITY_ID), centriodal/corner data (GRID_ID)).
$RESULT_TYPE	Specifies the result types used in the data column. Multiple result types, the animation source, and complex type can also be specified here. Specify the label for the data type followed by the type (Scalar, Vector, Tensor, Real, Complex, and so on). The label provided for the data type appears in the result name which is displayed in the Contour/Vector/Tensor panel. To recognize a result type as a Strain tensor, the label needs to contain the substring strain AND the format type should be (t) or (2t). If it does not contain the strain substring but only (t), then it is considered a Stress tensor (see the examples below): `$RESULT_TYPE = “abc strain result(t)”` → Strain Tensor 3D `$RESULT_TYPE = “abc result(t)”` → Stress Tensor 3D `$RESULT_TYPE = “def strain result(2t)”` → Strain Tensor 2D Also, the default Strain type in HWASCII is Engineering Strain. To switch to True strain, set the environment variable ALTAIR_HWASCII_IS_TRUESTRAIN=1.
$FREQUENCY	Specifies the frequency value in modal results. Units can be specified after the frequency value by separating them with a space.
$MODE	Specifies the mode number.
$TIME	Specifies the time value in transient results. Units can be specified after the time value by separating them with a space.
$INCLUDE	Specifies the include file path. The include file should contain only the data.
ALTAIR ASCII FILE	Specifies that the file is an ALTAIRASCII file.
(v), (t), (2t), (s)	Specifies result type format (like vector, 3D tensor, 2D tensor, and scalar).	(s)
Anim Source	With the result type, specifies the animation source. A node based vector result type should be the specified animation source.
(R/I) or (M/P)	Specifies the complex result type; either in the Real/Imaginary, or Magnitude/Phase format.

Note: If a keyword is specified in the file, it cannot be left blank. The default value of the keyword is assumed only when it is missing in the result file.
