CYCLIC4
Transforms cyclic components of load vectors or displacements
Output Data Blocks:
PK Load vector matrix in solution set components.
UX Solution vector matrix in cyclic components.
PHX Eigenvector matrix in cyclic components.
LAMA1 Appended eigenvalue summary table for all harmonics. Required for
normal modes analysis only. (APP='REIG' and PATH='BACK').
CASEBK1 Case Control table for data recovery requests for all harmonics.
Required for normal modes analysis only. (APP='REIG' and
PATH='BACK').
BACK1 Backward transformation matrix from cyclic to physical components
for all harmonics. Required for normal modes analysis only.
(APP='REIG' and PATH='BACK').
Parameters:
PATH Input-character-no default. Direction of cyclic transformation:
'FORE' forward (analysis)
'BACK' backward (data recovery)
HINDEX Input-integer-no default. Harmonic index.
APP Input-character-no default. Analysis type.
'STAT' statics
'REIG' normal modes
'BUCK' buckling
'FREQ' frequency response
NFREQ Input/output-integer-no default. The number of passes through
CYCLIC4. NFREQ is incremented by one on each execution of
CYCLIC4.
TOTALK Input-integer-default=0. Total number of harmonics. If TOTALK>0,
then CASEBK1 and BACK1 will be created. Required for normal
modes analysis only.
