MOMENT1

Bulk Data Entry

MOMENT1 – Static Moment, Alternate Form 1

Description

Defines a static moment by specification of a value and two grid points, which 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.

Field	Contents
SID	Load set identification number. (Integer > 0)
G	Grid point identification number. (Integer > 0)
M	Value of moment. (Real)
G1,G2	Grid point identification numbers. (Integer > 0; G1 ≠ G2)

Comments

1.	The static moment applied to grid point G is:

where, is a unit vector parallel to a vector from G1 to G2.

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