Bulk Data Entry Used to define a static force by specification of a value and four grid points that determine the direction.

It can also be used to define the EXCITEID field (Amplitude "A") of dynamic loads in RLOAD1, RLOAD2, TLOAD1 and TLOAD2 Bulk Data Entries. Additionally, the FORCE2 entry can be defined as Follower Loads in Large Displacement Nonlinear Analysis.

Field Contents SI Unit Example
SID Load set identification number.

(Integer > 0)

G Loaded Grid point identification number.

(Integer > 0)

F Value of force.


Gi Grid point identification numbers.

(Integer > 0; G1 and G2 may not be coincident; G3 and G4 cannot be coincident.)



  1. The static force applied to grid point G is:
    f = F N

    Where, N is a unit vector parallel to a vector calculated by the cross product of vectors from G1 to G2 and G3 to G4.

  2. This card is represented as a force load in HyperMesh.
