Bulk Data Entry Used to determine duplicate frequencies.

Parameter Values Description
DFREQ <Real>

Default = 10-5

DFREQ specified the threshold for the elimination of duplicate frequencies on all FREQi Bulk Data Entries. f N and f N 1 are considered duplicated if:
| f N f N 1 | < DFREQ * | f MAX f MIN |

Where, f MAX and f MIN are the maximum and minimum excitation frequencies of the combined FREQi entries.
