ConstraintEquations.cecyc(lowname='', highname='', nsector='', hindex='', tolerance='', kmove='', kpairs='', **kwargs)

Generates the constraint equations for a cyclic symmetry analysis

Mechanical APDL Command: CECYC

Parameters:

lownamestr

Name of a component for the nodes on the low angle edge of the sector. Enclosed in single quotes.

highnamestr

Name of a component for the nodes on the high angle edge of the sector. Enclosed in single quotes.

nsectorstr

Number of sectors in the complete 360 degrees.

hindexstr

Harmonic index to be represented by this set of constraint equations. If Hindex is -1, generate constraint equations for static cyclic symmetry. If HIndex is -2, generate constraint equations for static cyclic asymmetry.

tolerancestr

A positive tolerance is an absolute tolerance (length units), and a negative tolerance is a tolerance relative to the local element size.

kmoveint or str

• 0 - Nodes are not moved.

• 1 - HIGHNAME component nodes are moved to match LOWNAME component nodes exactly.

kpairsint or str

• 0 - Do not print paired nodes

• 1 - Print table of paired nodes

Notes

The analysis can be either modal cyclic symmetry or static cyclic symmetry.

The pair of nodes for which constraint equations are written are rotated into csys,1.
