6.3.3.1. Beam Group
To use beam group, outline or spline can be used as a base geometry. These lines are created with several control points. Total mass or density control each body mass and inertia.
6.3.3.1.1. Modeling Options
The user can create a joint group entity as follows.
Multi Point(Outline), WithDialog
Multi Point(Outline): Selects some points. To finish selecting points, click the empty space with the right mouse button choose Finish Operation on right-click menu. After finishing, these points are shaped to the outline geometry.
WithDialog: The user can define segments of created curve with Segments dialog box.
Multi Point(Spline), WithDialog
Multi Point (Spline): Selects some points. To finish selecting points, click the empty space with the right mouse button choose Finish Operation on right-click menu. After finishing, these points are shaped to the spline geometry.
WithDialog: The user can define segments of created curve with Segments dialog box.
Curve, WithDialog
Curve: Selects a curve.
WithDialog: The user can define segments of created curve with Segments dialog box.
Use Total Segment: If this option is selected, the user can make approximately equally spaced segments on the curve although there are multiple edges in a curve geometry.
No. of Segments: Defines the number of beam force between two continuous control points.
6.3.3.1.2. Properties
Young’s Modulus: Specify the young’s modulus of elasticity for the beam material. Refer to Beam Force.
Shear Modulus: Specify the shear modulus of the beam. Refer to Beam Force.
Density: Defines each body for mass and inertia.
Total Mass: Defines each body for mass and inertia.
Node Thickness: Defines the thickness for each body. The shape of cross section for each body changes depending on the selected type in Beam Library. It applies only graphically.
Library: In Beam Group, Beam Library also is supported. Refer to Beam Library.
If using Beam Library, total mass or density defined in the above edit box is ignored.
Color: Defines the color for each body.
Each Render: Selects the rendering mode to be displayed on Working Window when Each Render type is activated on Render Toolbar.
Damping: Enter the coefficient that determines the damping force given the velocity of the beam end points. Refer to Beam Force.
Update Force Property and Update Body property
This option determines beam information can be used as a group or not.
With these options, all properties that connected with each option are updated automatically. But if not, keep old data or direct input data even if the library data are changed.
Initial Velocity: Defines the initial velocity of all body of beam group. Refer to Body Page.
