9.7.10. FE Sets and Components

A set is a group of FE entities and it is useful because there are so many FE entities to select from in a typical FE mesh.

The user can create node sets, element sets and patch sets, which are easier to select than the individual entities.

A component is a group of the same element type or the same property.

• If two or more elements have the same type, then the element component is created automatically.

• This is also true of property components.

Sets and components, once created, are selectively displayed using the Display command.

• Add/Remove: Select nodes to add or remove for a node set.

• Add/Remove (Continuous): Select a patch or line to add or remove continuously with its own patch or line continuity in the angle tolerance for a node set.

  • Tolerance (Degree): Defines an angle tolerance to check patch or line continuity.

  • Check Reverse Direction: If this option is checked, nodes are selected regardless to normal direction of patches or lines in the angle tolerance.

  • Type Patch: Select a patch then continuously connected patches are added, and the nodes of the patches are selected.

  • Type Line: Select a line then continuously connected lines are added, and the nodes of the lines are selected.

• Add by Patch Set: Select a patch set to add to a node set. The node set defines all nodes of the selected patch set.

• Add by Element Set: Select an element set to add to a node set. The node set defines all nodes of the selected element set.

• Add by Line Set: Select a line set to add to a node set. The node set defines all nodes of the selected line set.

• Add by Multi FDR: Select multi FDR element to add to a node set. The node set defines all primary node of the selected FDR element.

• Add by Node IDs: Selects nodes to add or remove by Node IDs.

  • Initialize before Add: If this option is checked, initialize selected nodes.

  • Specific: Selects nodes by specific node ids with “-” and “,”.

  • Simple Rule: Selects nodes with Start ID, Increment, No. of Selection.

  • Start ID: Shows the starting node ID.

  • Increment: Shows the increment of node ID.

9.7.10.2. Patch Set

Figure 9.106 Patch Set dialog box

• Color: Selects a color to the patch set.

• Add/Remove: Selects patches to add or remove for a patch set.

• Add/Remove (Continuous): Selects a patch to add or remove for a patch set. RecurDyn/FFlex determines continuity of patches by Tolerance.

  • Tolerance (Degree): Defines an angle tolerance to check patch continuity.

  • Check Reverse Direction: If this option is checked, patches are selected regardless to normal direction of patches in the angle tolerance.

• Add/Remove (Select Front): Selects patches in front of the view direction to add or remove for a patch set.

• Add (Node Set): Selects a node set to add for a patch set. The patch set is defined patches of the selected node set.

• Add by Node IDs: Selects nodes to add or remove by Node IDs.

  • Start ID: Shows the starting node ID.

  • Increment: Shows the increment of node ID.

  • No. of Selection: Shows the number of selected node.

• Tolerance: Defines the tolerance to determine continuity of patches.

• Preview Normal: Previews the normal direction of the patch set.

• Normal Adjust: Adjusts the normal direction of the patch set.

  • Automatic

    • Auto Adjust: Adjusts the normal direction of the patch set automatically.

    • Switch: Switches from the normal direction of the patch set to the opposite direction.

  • Manual

    • Select Target: Selects the targeted patch set manually.

    • Switch: Switches from the normal direction of the targeted patch set to the opposite direction.

• No. of Patch: Shows the number of patches included in the patch set.

9.7.10.3. Element Set

• Color: Selects a color to the element set.

• Add/Remove: Selects elements to add or remove for an element set.

• Add/Remove (Continuous): Selects a patch to add or remove continuously with its own patch continuity in the angle tolerance for an element set.

  • Tolerance (Degree): Defines an angle tolerance to check patch continuity.

  • Check Reverse Direction: If this option is checked, elements are selected regardless to normal direction of patches in the angle tolerance.

• Add by Element IDs: Selects elements to add or remove by Element IDs.
