9.7.9. Creation

9.7.9.1. Node Creation

The node creation allows the user to define other nodes that are used for the primary node of the FDR element.

  • There are three ways to define the node position.

  • You can easily understand how to generate a node in a different way.

  • Create Method

    • Point: Defines the special location directly where the node was created.

    • 2-Nodes: Defines the node position with two different points. If you define these two points in a window, a new node is created in the center of these two points.

    • 3-Nodes: Defines the node position with three different points. (There exists a unique circle that passes the three points.) If you define these three points, a new node is created in the center of the circle that passes the three points.

  • Node ID: Defines a node ID to the node.

  • Position: Defines positions to specify the node.

9.7.9.2. Element Creation

One element can be created at a time. Beam2, Shell3, Shell4, Solid4, and Solid8 elements are possible to create.

  • Element Type: Selects a type to the element.

  • ID: Defines an element ID to the element.

  • Property: Defines the property to the element.

  • Secondary Nodes: Defines positions of nodes included in the element.

9.7.9.3. FDR Creation

The FDR element is the Force Distributing Rigid element.

  • There are RigidE type that defines rigid body element like RBE2 element and InterpE type that defines interpolation element like RBE3 in the other FE software.

  • This element plays a role to transfer force and moment from primary node to secondary nodes.

  • By using the FDR element in the FE Entity, you can easily create the FDR element by selecting the primary node and secondary nodes.

  • Type: Selects a type to the FDR element.

  • Primary Node: Defines a primary node to the FDR element.

  • Node Set: Defines a node set to the FDR element.

  • Element ID: Defines an element ID to the FDR element.

  • Property: Defines the property to the FDR element.

9.7.9.4. Mass Creation

The Mass element is used to represent a lumped mass.

  • By using the Mass element in the FE Entity, you can easily create the Mass element by selecting the node.

  • Node: Defines a target node to the Mass element.

  • Element ID: Defines an element ID to the Mass element.

  • Property: Defines the property to the Mass element.
