Creates a superelement from an existing superelement.
The name (case-sensitive) of the file containing the
original superelement matrix created by the generation pass (
Sename.SUB). The default is
the current Jobname. If
Sename is a number, it is the element number of a previously defined superelement
in the current use pass.
The reference number of the coordinate system to where the superelement is to be transferred. The default is the global Cartesian system. Transfer occurs from the active coordinate system.
The node offset. The default is zero. All new element
node numbers are offset from those on the original by
File name and directory path (248 characters maximum, including the characters needed for the directory path). An unspecified directory path defaults to the working directory; in this case, you can use all 248 characters for the file name.
This field requires input.
Filename extension (eight-character maximum).
The extension defaults to SUB.
Node location increments in the global Cartesian coordinate system. Defaults to zero.
Node rotation key:
The nodal coordinate systems of the
transferred superelement rotate into the
The nodal coordinate systems do not rotate. (That is, they remain fixed in their original global orientation.) The superelement matrices and load vectors are modified if any rotations occur.
You can create a superelement from an original by:
Transferring the original's geometry from the active
coordinate system into another coordinate system (
Offsetting its geometry in the global Cartesian coordinate
Offsetting its node numbers (
A combination of methods is valid. If you specify both the geometry transfer and the geometry offset, the transfer occurs first.
If you specify rotation of the transferred
superelement's nodal coordinate systems into the
KCNTO system (
NOROT = 0), the rotated nodes
cannot be coupled via the CP command; in this case,
issue the CE command instead. If you specify no rotation of the nodal coordinate systems
NOROT = 1) for models with displacement
degrees of freedom, and
KCNTO is not the
active system, the superelement
have six MDOF at each node that has MDOF; therefore, only elements
with all six structural DOFs are valid in such cases.
There is no limit to the number of copies that can be made of
a superelement, provided the copies are all generated from the same
original superelement. However, nested copies are limited to five.
In other words, the total number of different
Sename usages on the SETRAN and SESYMM commands is limited to five.
This command is not supported if the original superelement matrix was
created in a component mode synthesis analysis generation pass with the element results
calculation activated (
ELCALC = YES on
