Bulk Data Entry Defines a dynamic loading condition for frequency
response problems as a linear combination of load sets defined via RLOAD1
and RLOAD2 entries, or for transient problems as a linear combination of
load sets defined via TLOAD1 and TLOAD2 entries, or
acoustic source ACSRCE entries.

Comments
- Dynamic load sets must be selected in the
I/O Options or Subcase Information sections with
DLOAD=SID. (See I/O Options and Subcase
Information DLOAD entry).
- The load vector being defined by this entry
is given by:(1)
- Each L# must be unique
from any other L# on the same entry.
- SID must be unique from
all RLOAD1 and RLOAD2 or
TLOAD1 and TLOAD2 entries.
- A DLOAD entry may not
reference a set identification number defined by another DLOAD
entry.
- RLOAD1 and
RLOAD2 loads and TLOAD1 and
TLOAD2 loads may be combined only through the use of the
DLOAD entry.
- This card is represented as a load collector
in HyperMesh.
