Comments
- FREQ entries must be
selected with the I/O Options or Subcase Information command FREQUENCY = SID.
- All FREQi entries
with the same set identification numbers will be used. Duplicate frequencies
will be ignored.
and
are considered duplicated if: (1)
Where,
- DFREQ
- User parameter with a default of 10-5 *
-
- The maximum and minimum excitation frequencies of the combined
FREQi entries
- This card is represented as a load
collector in HyperMesh.
