Why does static cyclic symmetry analysis with symmetric load trigger many loadsteps?
The rotation axis is X represented by coordinate system 11.


CSYS,11 was defined as shown below:

LOCAL,R5.0,LOC, 11, 1, 0.00000000 , 0.00000000 , 0.00000000
LOCAL,R5.0,ANG, 11, 1, 90.0000000 , 90.0000000 , 0.00000000
LOCAL,R5.0,PRM, 11, 1, 1.00000000 , 1.00000000
CSCIR, 11, 0, 0

The problem disappears if I replace this input with the following:

LOCAL,11,1,,,,,,90 ! thzx=90

Apparently the cyclic logic is checking the input rotation angles
not the final direction.
