CREATE ELEMENT
This menu lists the options used to create elements via the connection of selected nodes or points. The element types supported are those recognized by LS-DYNA. The element types are shown in Figure 6.3.15.

1. BEAM
Select two points or nodes by cursor in screen.
Define the property axis by selecting a third node/point or defining the vector:
BY NODE
BY POINT
BY VECTOR
Up to three values may be entered in the next dialog window to define a vector in the bar local XY plane. The local Y-axis of the bar will be plotted at the first node of the bar element as it is generated.
2. NODAL RIGID BODY
The user selects nodes or points in the INPUT COORDINATE dialog window. The NODAL RIGID BODY is created automatically in the current part once DONE is selected.
3. SPOT WELD
The SPOT WELD is created automatically in the current part after two nodes or points are selected in the INPUT COORDINATE dialog window.
4. SHELL
This function allows the user to create quadrilateral and triangular elements in the current part. The INPUT COORDINATE dialog window appears.
CREATE QUADRILATERAL ELEMENT
The element is created automatically once four nodes or points are selected in the INPUT COORDINATE dialog window.
CREATE TRIANGULAR ELEMENT
The user must click DONE after three nodes or points are selected in the INPUT COORDINATE dialog window.
5. SOLID
This function allows the user to create hexahedron (cube), pentahedron (wedge), and tetrahedron element by using options in the INPUT COORDINATE dialog window.
TETRAHEDRON
Select four nodes/points and select DONE. The first three nodes define the base of the tetrahedron. They should follow the right hand rule to point to the fourth node.
PENTAHEDRON
Select six nodes/points (pick the second set of three nodes/points in the same order as the first set) and select DONE. The first three nodes define the bottom face of the pentahedron. They should follow the right hand rule to point to the top face.
HEXAHEDRON
HEXAHEDRON
Select eight nodes/points (pick the second set of four nodes/points in the same order as the first set) and element will be created automatically. The first four nodes define the bottom face of the hexahedron. They should follow the right hand rule to point to the top face.
6. SPRING/DUMPER (2 NODE ELEMENTS)
The element is created after two nodes/points are selected.
7. MASS (1 NODE ELEMENT)
Enter value of the mass in the field of next dialog window.
Select nodes/points as the mass element by using options in the INPUT COORDINATE dialog window.
8. THICK SHELL
The element is created after eight nodes/points are selected (the second set of four nodes/points is in same order of the first set).
