Field Contents SI Unit Example
C Component number.

(Integer zero or blank for scalar points, or up to 6 unique digits (0 < integer ≤ 6) may be placed in the field with no embedded blanks for grid points. The components refer to the coordinate system referenced by the grid points.)

Gi Grid or scalar point identification numbers.

(Integer > 0, for THRU option, G1 < G2)



  1. If the alternate format is used, all points in the sequence G1 through G2 are not required to exist, but there must be at least one boundary degree-of-freedom for the model, or a fatal error will result. Any grids implied in the THRU that do not exist will collectively produce a warning message, but will otherwise be ignored.
  2. Refer to Direct Matrix Input in the User Guide for more information on the use of this card.
  3. A fatal error will be issued if the input contains ASET or ASET1, but PARAM,EXTOUT is not given.
  4. When the SPSYNTAX setting on the SYSSETTING I/O Option is set to CHECK (default) or MIXED, it is allowed that when grid lists are provided for a given component, that the grid references be either scalar points (SPOINT) or structural grid points (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 SPSYNTAX is set to STRICT it is required for grid/component pairs (G#/C#) that the component be 0 or blank when the grid references are to scalar points (SPOINT), and that the component be > 1 when the grid references are to structural grid points (GRID). When the component is greater than 1, the grid references must always be a structural grid (GRID).
  5. This card is represented as a constraint load in HyperMesh.
