FATAL ERROR: T2116
|
UNABLE TO GENERATE CYCLIC SYMMETRIC BOUNDARY CONDITIONS
|
|
|
Cause:
|
A cyclic symmetric boundary condition generation command failed using the parameters listed on a
CYSYMGENERATE Case Control command or the
CYSYMGEN and
CYSYMTOL model parameters. The status codes have the following meaning:
|
Code
|
Meaning
|
|
1
|
Symmetry boundary non-planar or misaligned.
|
|
2
|
Specified coordinate system does not exist or is not cylindrical.
|
|
3
|
No grid points found with specified coordinate system.
|
|
4
|
No grid points found on one or both symmetry boundaries.
|
|
5
|
Unable to generate multipoint constraint equations.
|
|
|
|
Action:
|
Perform the following depending on the status code given:
|
Code
|
Meaning
|
|
1
|
Correct the model cyclic symmetry boundaries so that the grid theta coordinate values are the same for each plane.
|
|
2
|
Make sure a valid cylindrical coordinate system is defined and referenced on either the CYSYMGENERATE Case Control command or the CYSYMGEN and CYSYMTOL model parameters.
|
|
3
|
Correct the model so that the cyclic symmetry boundary grid points reference the cyclic symmetric cylindrical coordinate system in the grid displacement system field of the GRID Bulk Data entry.
|
|
4
|
See action for codes 1-3.
|
|
5
|
See action for codes 1-3.
|

Remarks:
|
See Autodesk Nastran Reference Guide, Section 3,
Case Control, for command format, Section 4,
Bulk Data, for entry format, and Section 5,
Parameters, for more information.
