Field

Contents

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)

N1, N2, N3

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)
