*SYMMETRIC MODEL GENERATION
Optional parameters:
ELEMENT OFFSET
Set this parameter equal to an integer to define the offset for element numbering. When the
REVOLVE parameter is used, the offset is added to each element number on the previous
cross-section to obtain the numbering of the elements on the next cross-section, starting at the
reference cross-section,
. The reference cross-section uses the same numbering as the
original axisymmetric model. When the REFLECT parameter is used, the offset is added to the
original element numbers to define the numbering on the reflected part. The default and minimum
value is the largest element number used in the original model.
FILE NAME
Set this parameter equal to the name of an external file (without an extension) to which keyword
and data lines for the model definition will be written. The extension .axi will be added to the
file name provided by the user. See “Input syntax rules,” Section 1.2.1 of the ABAQUS Analysis
User’s Manual, for the syntax of such file names.
NODE OFFSET
Set this parameter equal to an integer to define the offset used for node numbering. When the
REVOLVE parameter is used, the offset is added to each node number on the previous cross-section
to obtain the numbering of the nodes on the next cross-section, starting at the reference cross-section,
. The reference cross-section uses the same numbering as the original axisymmetric model.
When the REFLECT parameter is used, the offset is added to the original node numbers to define
the numbering on the reflected part. The default and minimum value is the largest node number
used in the original model.
TOLERANCE
Set this parameter equal to the distance to be used in the search for duplicate nodes. Duplicate nodes
on the axis of revolution of a revolved model and on the connection plane between the two parts of
a reflected model will be eliminated. The default is 1.0% of the average element dimension.
Data lines if each generated sector in the periodic model has a constant angle
(PERIODIC=CONSTANT):
First line:
1. X-coordinate of point a.
2. Y-coordinate of point a.
3. Z-coordinate of point a.
4. X-coordinate of point b.
5. Y-coordinate of point b.
6. Z-coordinate of point b.
