     No: Shows the Index of belt bodies.

     Check button: If this button is checked, a specified BC is activated in the belt body. Or not, the specified BC is deactivated.

     Name: Defines the name of belt bodies belongs to the Beam Belt.

     BC: Determines the fixed D.O.F of each belt body. (link to below apply the following BC)

    Boundary Condition

Translation & Rotational D.O.F: Degree of Freedom type.

X, Y, Z: The components of translational and rotational D.O.F. The components are determined in the belt body reference frame.

 

     Selection by Simple Rule: Accesses the Selection dialog box that supports a simple rule to select many belt bodies at the same time. The belt bodies can be selected by following simple rule.

    Initialize before Update: If this button is checked and click the Update, only the check boxes of belt bodies selected by user-defined rule are activated. Or not, the check boxes of pre-selected belt bodies and belt bodies selected by user-defined rule are activated.

    Start Index: Shows the starting index in the simple rule.

    Increment in Index: Shows the increment of index in the simple rule.

    Number of Selection: Shows the number of selected belt bodies in the simple rule.

    Apply the following Boundary Condition: Determines the fixed D.O.F of all selected belt bodies.

Translation & Rotational D.O.F: Degree of Freedom type.

x, y, z: The components of translational and rotational D.O.F. The components are determined in the belt body reference frame.

 

    Check button: If this is checked, the specified component is fixed to the ground.

    Update: Updates the list with the selected belt bodies.

    Close: Does not update the list.

 

     All/Nothing: The check boxes of all belt bodies in the list are activated or deactivated.

     Add + Navigation: If the user selects the Add option and clicks the navigation button, the user can select nodes from the screen and a boundary condition is applied on the nodes.

     Remove + Navigation: If the user selects the Remove option and clicks the navigation button, the user can select nodes from the screen and a boundary condition is not applied on the nodes.

     Add or Remove + Navigation: If the user selects the Add or Remove option and clicks the navigation button, the user can select nodes from the screen and a boundary condition is applied or not on the nodes.

     Orientation Reference Frame: If the user selects Node option, then the orientation reference frame of the Boundary Condition is set with each node. If the user selects Inertia Marker, then the orientation reference frame of the Boundary Condition is set with Ground.Inertia Marker of the current system. Default is Node.
