# DELAY

Bulk Data Entry Defines the time delay term $\tau$ in the equations of the dynamic loading function. DELAY is used in conjunction with RLOAD1, RLOAD2, TLOAD1, and TLOAD2 entries.

T1, T2 Time delay term, $\tau$ , for designated point and component.

No default (Real)

## Comments

1. One or two dynamic load time delays may be defined on a single entry.
2. SID must also be specified on a RLOAD1, RLOAD2, TLOAD1, or TLOAD2 entry. See those entry descriptions for the formulae that define the manner in which the time delay term, $\tau$ , is used.
3. A DAREA entry should be used to define a load at P# and C#. This condition is not required, if SPCD is applied to these degrees of freedom.
4. When the SPSYNTAX setting on the SYSSETTING I/O Option is set to CHECK (default) or STRICT, it is required for grid/component pairs (G#/C#) that the component be 0 or blank when the grid reference is a scalar point (SPOINT), and that the component be ≥ 1 when the grid reference is a structural grid point (GRID). When SPSYNTAX is set to MIXED, it is allowed for grid/component pairs (G#/C#) that the grid reference be either a scalar point (SPOINT) or a structural grid point (GRID) when the component is 0, 1 or blank; interpreting all of these as 0 for scalar points and as 1 for structural grids. When the component is greater than 1, the grid reference must always be a structural grid (GRID).
