*PARAMETER SHAPE VARIATION
16.3 *PARAMETER SHAPE VARIATION: Define parametric shape variations.
This option is used to define parametric shape variations.
Products: ABAQUS/Standard ABAQUS/Explicit
Type: Model data
Level: Part, Part instance

Required parameter:
PARAMETER
Set this keyword parameter equal to the name of the parameter to which the shape variation data
refer. If this parameter is also a design parameter, the shape variations are used to define the design
gradients of the nodal coordinates for design sensitivity analysis.
Optional parameters (mutually exclusive-if neither parameter is specified, ABAQUS assumes
that the shape variation data will be entered directly on the data lines):
FILE
Set this parameter equal to the name of the results file from a previous ABAQUS/Standard analysis
containing either the mode shapes from a *BUCKLE or *FREQUENCY analysis or the nodal
displacements from a *STATIC analysis. This option cannot be used for models defined in terms of
an assembly of part instances.
INPUT
Set this parameter equal to the name of the alternate input file containing the shape variation data.
See “Input syntax rules,” Section 1.2.1 of the ABAQUS Analysis User’s Manual, for the syntax of
such file names.
Required parameter if the FILE parameter is used:
STEP
Set this parameter equal to the step number (in the analysis whose results file is being used as input
to this option) from which the modal or displacement data are to be read.
