FIXED_CL cltarg [DALIM dalim] [RELAX rlxalph] [FREQENCY alfafreq] \ [HISTORY {ON|OFF}] [START [AT] istart] |
This keyword may be used to vary the angle of attack to obtain a specified lift coefficient for surface(s) defined by the SURFACE and/or SUBSET keywords (with FORCE specified) in the LOADS keyword block. Note that the specified lift coefficient is the total for all surfaces combined.
cltarg | The desired lift coefficient. The default is 0.0. | ||
dalim | Limit in the angle of attack change allowed each update (degrees). The default is 0.2 degrees. | ||
rlxalph | Relaxation parameter. The default is 1.0, for no relaxation. | ||
alfafreq | Update frequency, in cycles. The default is 1, to update every cycle. | ||
istart | Starting cycle. The default is 1, to start on the first cycle. |
By default, the angle of attack changes are written to the .lis file. Specifying HISTORY OFF will prevent this.
