*INSTANCE

Begin an instance definition.

This option is used to instance a part within an assembly. It must be used in conjunction with the ASSEMBLY and END INSTANCE options. If the instance is not imported from a previous analysis, the INSTANCE option must be used in conjunction with the PART option.

When importing a part instance from a previous analysis, the INSTANCE option must be used in conjunction with the IMPORT option. You can define a new position for an imported instance and import an instance more than once.

When importing a part instance from a previous analysis, the INSTANCE option can be used in conjunction with the IMPORT SURFACE option to import surfaces selectively or to import all surfaces by default.

TypeModel data

LevelAssembly

Required parameters if the instance is not imported from a previous analysis

NAME

Set this parameter equal to a label that will be used to refer to the instance.

PART

Set this parameter equal to the name of the part being instanced.

Required parameter if the instance is to be imported once from a previous analysis

INSTANCE

Set this parameter equal to the name of the instance to be imported from the previous analysis.

Required parameters if the instance is to be imported more than once from a previous analysis

NAME

Set this parameter equal to a new label that will be used to refer to the instance.

INSTANCE

Set this parameter equal to the old name of the instance to be imported from the previous analysis.

Required parameter if importing instances from multiple previous analyses (Abaqus/Explicit only); optional parameter if importing instances from a single previous analysis

LIBRARY

Set this parameter equal to a value that specifies the previous analysis from which to import the instance. You can specify the name of the previous analysis or the name including a full path. If no path is specified, all input files and result files from the previous analyses must reside in the current (working) directory.

When importing from a single previous analysis, if the LIBRARY parameter is omitted, you must specify the job name of the previous analysis on the command line using the oldjob option (see ). If both methods are used, the LIBRARY parameter takes precedence over the command line specification.

When importing from multiple previous analyses, set this parameter equal to the job name. You should not use the oldjob option on the command line.

Data line to translate an instance

First (and only) line

  1. Value of the translation to be applied in the X-direction.

  2. Value of the translation to be applied in the Y-direction.

  3. Value of the translation to be applied in the Z-direction.

Data lines to translate and/or rotate an instance

First line

  1. Value of the translation to be applied in the X-direction.

  2. Value of the translation to be applied in the Y-direction.

  3. Value of the translation to be applied in the Z-direction.

Enter values of zero to apply a pure rotation.

Second line

  1. X-coordinate of point a on the axis of rotation (see Figure 1).

  2. Y-coordinate of point a on the axis of rotation.

  3. Z-coordinate of point a on the axis of rotation.

  4. X-coordinate of point b on the axis of rotation.

  5. Y-coordinate of point b on the axis of rotation.

  6. Z-coordinate of point b on the axis of rotation.

  7. Angle of rotation about the axis a–b, in degrees.

If both translation and rotation are specified, translation is applied before rotation.
