|CYCLES numcyc [PRINT [FREQUENCY] freq]|
This keyword is used to set the number of cycles numcyc, and is required in the input data file. By default each cycle has five flowfield iterations in each zone for structured grids, and one for unstructured grids, but this may be changed using the ITERATIONS keyword.
Cycle time information will be written to the .lis file every freq cycles, starting with the first cycle. The default is every cycle.
For structured grids, residuals will also be written to the .lis file every freq cycles, starting with the first cycle, but only for iterations consistent with the PRINT FREQUENCY specified with the ITERATIONS keyword. For unstructured grids, residuals will be written to the .lis file every cycle.
Note that this does not affect integrated properties specified using the LOADS keyword block. The print frequency for integrated properties is controlled by the PRINT keyword in the LOADS keyword block.
If the user specifies
CYCLES 1000 PRINT FREQUENCY 10 ITERATIONS PER CYCLE 10 PRINT FREQUENCY 10cycle time information will be printed for cycles 1, 11, 21, etc. For structured grids, residuals will only be printed for iterations 10 (in cycle 1), 110 (cycle 11), 210 (cycle 21), etc.
