ABAQUS Keywords Reference Manual  

*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.

Products: ABAQUS/Standard  ABAQUS/Explicit  

Type: Model data

Level: Assembly  

References:

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 from a previous analysis: 

INSTANCE

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

Optional import parameter: 

LIBRARY

Set this parameter equal to the name of the previous analysis from which the instance should be imported. The previous analysis output database (.odb) file should reside in the current (working) directory. If the LIBRARY parameter is omitted, the job name of the previous analysis must be specified on the command line using the oldjob parameter (see “Execution procedure for ABAQUS/Standard and ABAQUS/Explicit,” Section 3.2.2 of the ABAQUS Analysis User's Manual). If both methods are used, the command line specification will take precedence over the LIBRARY parameter.

Data line to translate an instance that is not imported from a previous analysis: 

First (and only) line:

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

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

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

Data lines to translate and/or rotate an instance that is not imported from a previous analysis: 

First line:

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

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

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

Enter values of zero to apply a pure rotation.

Second line:

  1. -coordinate of point on the axis of rotation (see Figure 9.17–1).

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

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

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

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

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

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

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

There are no data lines for an instance that is imported from a previous analysis.
