Property identification number.

First grid identification number.

Second grid identification number ().

1.	The gradient deficient NLFE beam element is a type of line element that has two nodes.

2.	Each element has a unique identification number with respect to other gradient deficient NLFE beam element.

3.	This element can resist the axial, shear, torsion and bending loads.

4.	Linear and nonlinear general elastic material models can be used with the beam element.

5.	Figures 1 shows the NLFE gradient deficient beam element and its nodal coordinates.

6.	PBEAM9 is used to define the geometric properties and material card ID of the element BEAM9.

The example demonstrates the definition of a BEAM9 element.
