Create/Modify Nonlinear Beam

(Template Builder) Build → Parts → Nonlinear Beam → New/Modify Shared Dialog Box

Creates or modifies a nonlinear beam.

For the option:	Do the following:
Tips on Entering Object Names in Text Boxes.
Nonlinear Beam Name	If creating a nonlinear beam, enter a string that defines its name. If modifying a nonlinear beam, enter its database name.
Beam Method	Select a beam method. Default is set to Discrete Flexible Link.
Coordinate References (available in create mode only)	Enter the points that define the ends of the cylinders that comprise the nonlinear beam. For symmetric beams, enter the coordinate references starting from the farthest away from the centerline. For every two coordinates you enter, your template-based product defines a segment of the nonlinear beam. The series of hardpoints or construction frames you enter in the Coordinate Reference text box defines a series of segments. This series of segments comprise the chain that is the nonlinear beam.
Shape	Select a shape for the beam. ■cylindrical ■rectangular
Properties	Select a mass property method: ■Auto Calculate ■User Entered
Type of Beam	■flexible ■rigid
If you set Shape to cylindrical, your template-based product enables the following options:
Outer Radius	Specify the outer radius of the nonlinear beam.
Inner Radius	Specify the inner radius of the nonlinear beam.
If you set Shape to rectangular, your template-based product enables the following options:
Height	Specify the height of the nonlinear beam.
Width	Specify the width of the nonlinear beam.
If you set Properties to User Entered, your template-based product enables the following options:
Ixx	Enter the area moment of inertia.
Iyy	Enter the area moment of inertia.
Izz	Enter the area moment of inertia.
Area	Enter the cross-sectional area.
If you set Type of Beam to flexible, your template-based product enables the following option:
Damping Ratio	Enter the damping ratio for the beam elements for the flexible nonlinear beam.
Material Type	Select the nonlinear beam material. Your template-based product determines the mass properties according to the current density for the material you selected.
Beam Formulation	Specifies the theory to be used to define the force this element will apply. By default the LINEAR theory is used. If the NONLINEAR option is used, the full non linear Euler-Bernoulli theory is used. If the STRING option is used, a simplified non linear theory is used. The simplified non linear theory may speed up your simulations with little performance penalties.
If FE Part method is selected, the following options will be displayed:
Coordinate References (available in create mode only)	Enter the points that define the ends of the cylinders that comprise the nonlinear beam. For every two coordinates you enter, your template-based product defines a segment of the nonlinear beam. The series of hardpoints or construction frames you enter in the Coordinate Reference text box defines a series of segments. This series of segments comprise the chain that is the nonlinear beam.
Shape	Select a shape for the beam. ■cylindrical ■rectangular
Properties	Select a mass property method: ■Auto Calculate ■User Entered
If you set Shape to cylindrical, your template-based product enables the following options:
Outer Radius	Specify the outer radius of the nonlinear beam.
Inner Radius	Specify the inner radius of the nonlinear beam.
If you set Shape to rectangular, your template-based product enables the following options:
Height	Specify the height of the nonlinear beam.
Width	Specify the width of the nonlinear beam.
Damping Ratio (Stiffness)	Enter the damping ratio as a function of stiffness.
Damping Ratio (Mass)	Enter the damping ratio as a function of mass.
Evenly Spaced Nodes	Select to evenly space the nodes.
If you set Properties to User Entered, your template-based product enables the following options:
Iyy	Enter the area moment of inertia.
Izz	Enter the area moment of inertia.
Iyz	Enter the area moment of inertia.
Jxx	Enter the area moment of inertia.
Area	Enter the cross-sectional area.
Material Type	Enter the material type.
Color	Select the color for the nonlinear beam graphics.
	Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments: ■If recording comments for modeling entities in Standard Interface, your template-based product displays the Entity Comments dialog box. ■If recording comments for any other entity type, your template-based product displays the Modify Comment dialog box. Learn about Recording Comments.
