CYCLES - Number of solution cycles

CYCLES ncyc [PRINT FREQUENCY freq]

This keyword is used to set the number of cycles ncyc, and is required in the input data file. By default each cycle has five flowfield iterations in all zones, 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. 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.

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.

Example

If the user specifies

   CYCLES 1000 PRINT FREQUENCY 10
   ITERATIONS PER CYCLE 10 PRINT FREQUENCY 10

cycle time information will be printed for cycles 1, 11, 21, etc. Residuals will be printed for iterations 10 (in cycle 1), 110 (cycle 11), 210 (cycle 21), etc.
