Bulk Data Entry Defines scale (area) factors for dynamic loads. DAREA is used in conjunction with RLOAD1, RLOAD2, TLOAD1, and TLOAD2 entries.

Field Contents SI Unit Example
SID Identification number.

No default (Integer > 0)

P1, P2# Grid or scalar point identification number.

No default (Integer > 0)

C1, C2# Component number. Component numbers refer to the displacement coordinate system.

No default (Integer 1 through 6, or 0 for scalar points)

A1, A2# Scale (area) factor.

No default (Real)



  1. One or two scale factors may be defined on a single entry.
  2. Refer to RLOAD1, RLOAD2, TLOAD1, or TLOAD2 entries for the formula that define the scale factor A#.
  3. 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).
