Bulk Data Entry Defines the coefficients of a power series for use in
generating frequency-dependent and time-dependent dynamic loads. Also contains parametric data
for use with the table.

Comments
- At
least one continuation entry must be
specified.
- The
end of the table is indicated by the existence of
ENDT in either of the two fields
following the last entry. An error is detected if
any continuations follow the entry containing the
end-of-table flag ENDT.
-
TABLED4 uses the algorithm:
Where,
-
- Input to the table
-
- Is returned
-
- Number of pairs
Whenever
, use X3 for
; whenever
, use X4 for
. There are N + 1 entries in the table. There are no error
returns from this table look-up procedure.
- For
frequency-dependent loads, x#
is measured in cycles per unit time.
- This
card is represented as a load collector in
HyperMesh.
