*BEAM3

Data format:

An arbitrary number of lines with 7 parameters each, as follows:

NEL JO JK JE IPRO IMAT XLO
...

Status:

Optional

Purpose:

To define 3 nodes beam elements (6 degrees of freedom per node).

Restrictions:

The total number of elements (all types) may not exceed MAXEL . The nodes JO, JK and JE must have been previously defined

Details :

Parameter	Description
NEL	Identification number of the element
JO	Origin node of the element
JK	Intermediate node of the element
JE	End node of the element
IPRO	Index in the table of elementary mechanical and geometrical properties (previously defined by keyword BEAMPRO or RIGIPRO)
IMAT	Material index (previously defined by keyword *MAT)
XLO	Element length. Note: If XLO=0, the element length is taken from the corresponding properties keyword (referred by IPRO). If XL0 is still null the element length is the initial distance between the nodes composing it.

Note: This element is given in an initially unstressed configuration.
