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

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