CYCLIC4
Transforms cyclic components of load vectors or displacements
CYCLIC4 Transforms cyclic components of load vectors or displacements
Transforms the cyclic components of load vectors associated with a particular
harmonic into solution set load vectors in the forward path. In the backward path, the
solution set displacement vectors will be transformed into cyclic components
associated with the particular harmonic and appended to previous harmonic
solutions.
