Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| SID | Load set identification
number. No default (Integer > 0) |
|
| G1 | Grid point identification
number where the action force is applied. No default (Integer > 0) |
|
| CID | Coordinate system
identification number. Blank or 0 infer the basic coordinate
system. Default = 0 (Integer ≥ 0, or blank) |
|
| EID | Expression identification
number of the MBVAR entry that gives the load
measured in the coordinate system defined by
CID. No default (Integer > 0) |
|
| G3 | Grid point identification
number to optionally supply N1,
N2, N3 in conjunction with
G1. (Integer > 0) |
|
| N, N, N | Defines the direction of
the force vector. At least one of the vector components must be
non-zero. Default = 0.0 (Real) |
|
| G2 | Grid point identification
number where the reaction force is applied. If blank or zero, the
force is an action-only force. Default = 0 (Integer ≥ 0) |
|
| G4 | Grid point identification
number whose parent body hosts the coordinate system with respect to
which the force is defined. The force vector changes direction with
the orientation of the body. If undefined, the force is defined with respect to the ground body (that is the basic coordinate systems). Default = blank (Integer ≥ 0 or blank) |
