PARAM, DFREQ

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.
