Default Value |
2 |
|
Description |
Defines the number of periodic cycles of initialization of the Fourier Transform model. The purpose of the cycles is to initialize the Fourier coefficients before the start of phase shifting. The length of these cycles is the period of the disturbance being modeled. This parameter applies only to cases that do not model any transient rotor stator interfaces using the Fourier Transform model. |

|
Description |
This parameter controls the number of phase shifted startup cycles of the Fourier Transform model. The purpose of the cycles is to limit the maximum number of coefficient loops at the start of phase shifting. The length of these cycles is the period of the disturbance being modeled. This parameter is applicable to inlet disturbance or flutter cases. |

Description |
This parameter selects between different built-in algorithms for improving the rate of solution convergence. This parameter has no effect on the results obtained for a converged solution. Set this parameter to 0 to revert to the behavior of Release 2019 R3 and earlier. Other valid values are: 1, 2, 3. If your case fails to converge, changing the value of this parameter might help. |
