# MOMENT2

Bulk Data Entry Defines a static moment by specification of a value and four grid points, which determines the direction.

Attention: Valid for Implicit and Explicit Analysis

It can also be used to define the EXCITEID field (Amplitude A) of dynamic loads in RLOAD1, RLOAD2, TLOAD1 and TLOAD2 Bulk Data Entries.

## Definitions

Field Contents SI Unit Example
SID Load set identification number.

(Integer > 0)

G Loaded grid point identification number.

(Integer > 0)

M Value of moment.

(Real)

G1, G2, G3, G4 Grid point identification numbers.

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

$\stackrel{\to }{\text{m}}=\text{M}\stackrel{\to }{\text{N}}$
Where, $\stackrel{\to }{\text{N}}$ is a unit vector parallel to a vector calculated from the cross product of the vectors from G1 to G2 and G3 to G4.
