SESYMM, Sename, Ncomp, INC, File, Ext, --
Performs a symmetry operation on a superelement within the use pass.

Compatible Products: – | Pro | Premium | Enterprise | Ent PP | Ent Solver | –


The name (case-sensitive) of the superelement matrix file created by the substructure generation pass (Sename.SUB). Defaults to the current Jobname. If a number, it is the element number of a previously defined superelement in the current use pass.


Symmetry key:



X symmetry (default).



Y symmetry.



Z symmetry.


Increment all nodes in the superelement by INC.


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 must be input.


Filename extension (eight-character maximum).

The extension defaults to SUB.


Unused field.


Performs a symmetry operation on a superelement within the substructure use pass by reversing the sign of component Ncomp in the global Cartesian coordinate system. The node numbers are incremented by INC. The new superelement is written to File.SUB in the current directory (by default). All master node nodal coordinate systems must be global Cartesian (no rotated nodes allowed).

The maximum number of transformations for a given superelement is five (including SETRAN, SESYMM, and the large rotation transformation if NLGEOM is ON in the use pass).

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 CMSOPT).

Distributed ANSYS Restriction This command is not supported in Distributed ANSYS.
