*PARAMETER SHAPE VARIATION
Optional parameters if the FILE parameter is used:
INC
Set this parameter equal to the increment number (in the analysis whose resultsfile is being used as
input to this option) from which the displacementdata are to be read. If this parameter is omitted,
ABAQUS will read the data from the last increment available for the specified step onthe results
file.
MODE
Setthis parameter equal to the mode number (in the analysis whose results file is being used as input
to this option) from which the modal data are to be read. If this parameter is omitted, ABAQUS
will read the data from the first mode availablefor the specified step on the results file.
NSET
Set this parameter equal to the node set to which the shape variation values are to be appli ed. If this
parameter is omitted, the shape variation will be applied to all nodes inthe model.
Optional parameter if the FILE parameter is omitted:
SYSTEM
Set SYSTEM=R (default) to specify the shape variation as values of Cartesian coordinates. Set
SYSTEM=C to specify theshape variation as values of cylindrical coordinates. Set SYSTEM=S to
specify the shape variation as values of sphericalcoordinates. SeeFigure 16.3–1.
The SYSTEM parameter is entirely local to this option and should not be confused with the
*SYSTEM option. As the data lines are read, the shape variation values specified are transformed
to the global rectangular Cartesiancoordinate system. This transformationrequires that the object
be centered about the origin of the global coordinate system; i.e., the *SYSTEM option should
be off when specifying shape variations as values using either cylindrical or spheric al coordinates.
The details of how the shape variation is computed in particular coordinate system s are given in
“Parametric shape variation,” Section 2.1.2of the ABAQUS Analysis User ’sManual.
Data lines to define the shape variation if the FILEand INPUT parameters are omitted:
First line:
1. Nodenumber or node set.
2. Component of shape variation in the first coordinate direction.
3. Componentof shape variation in the second coordinate direction.
4. Componentof shape variation in the third coordinate direction.
5. Shape variation in the first normal component.
6. Shapevariation in the second normal component.
7. Shape variation in the third normal component.
Repeat this data line as often as necessary to define the shape variation. The data given on this data
line cannot be parameterized.
