/BEAM
Block Format Keyword Describes the beam elements. Two properties (/PROP/TYPE3 (BEAM) and /PROP/TYPE18 (INT_BEAM)) are available for this beam element. The properties describing a beam element are all defined in a local beam coordinate system.

Comments
- The identifier (ID) must be unique in each element family, but it is advised for each element type to have a unique element identifier in the global model.
- More than one beam block may be used to define a part.
- Any number of beams may be defined in one block.
- Local coordinate system of beam:
Nodes 1 and 2 define local X-axis.
Nodes 1, 2 and 3 define local axis (X,Y) plane at time t =0.
The third node is only used to define initial local frame position.
Z axis is orthogonal to (X,Y) plane.
