Create Panel Structural Elements

The Panel tool recognizes metallic panels or composite panels, which lead to two different configs as the structural property and method available for these configs are different.

  1. From the Certification ribbon, click the Panel tool.

    Figure 1.
  2. When Structural elements are created, a structural property can be selected. Click to define how properties are assigned.
    Each structural element can have a structural property assigned to it (optional) in order to run method.
    Single property
    Assigns the same structuralproperty entity to all designpoints.
    Duplicate and assign property to all
    Creates a new instance of selected structuralproperty and assigns the copy to all designpoints.
    Duplicate and assign property per designpoint
    Creates a new instance of selected structuralproperty per designpoint entity.
    This option performs a deep copy, meaning the structural property's references, such as materiel/property, are also copied. Each structural property generated is fully independent.
    This is useful for design exploration where you will update structural properties separately.
  3. Set the entity type on the first selector to Elements.
    If only shell elements are selected, panels are recognized as shell elements by face until T-junctions.
    If the selection includes both shells and bar2/rod elements, panels are recognized as shells surrounded by 1D.

    While generating stuctural elements of config panel or Generic, you can split them based on the element’s property or the element’s component. On the guide bar, click to select a Split by option.

    The split operation is done after panel detection method from shells and attached 1D.
    • If split = none, panels are detected based on the description above.
    • If split = by property/by component.
    The panels are first detected based on T-junctions and further split based on shell property/component.

  4. In the microdialog, select the type of panel to detect in the model.
    • Panel metallic
    • Panel composite

    Choosing one or the other has no effect on the selection (elements remain selected and highlighted). After confirming, panels are detected based on the shell property type (PSHELL vs PCOMP/PCOMPG/PCOMP).

    Switching the type also switches the current type in the Certification Browser and refreshes the existing list.

  5. Optional: Select a destination DesignPointSet to hold newly created designpoints.
    If no set is selected, a new one is created based on the active panel type selected in the microdialog.

    If you enter this menu from the Certification Browser context menu using Auto DDP, the selector is pre-populated with the selected designpointset.

  6. Specify a structuralproperty entity if the Absorb FE Property checkbox is unselected.
    Otherwise, the tool attempts to absorb a structural property from the element closest to the panel’s center. This structural property is then unique for all elements belonging to the panel.
    Panel metallic retains thickness and material from the reference element.

    Panel composite creates a copy of the composite property from the reference element.

    The panel width/length and radius of curvature are approximately calculated from the FE model.

  7. On the guide bar, click one of the following:
    • - Save changes and stay in the tool.
    • - Save changes and close the tool.
