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. |
