Define DLOAD on: Element Sets

Use the Define DLOAD on: Element sets option to define various DLOAD types on element sets. The element set names are used in the *DLOAD data lines instead of the individual elements. Unlike Abaqus surfaces in HyperMesh, you can combine element sets with individual element IDs in the same *DLOAD card.

Note:

There is no graphical display in HyperMesh for loads created on sets. Therefore, when you review a load collector in the Step Manager, only loads created on individual entities are highlighted. For loads defined on sets, the underlying nodes or elements are highlighted.

step_mgr_define_elem_sets

This dialog contains a element sets menu with a list of the existing element sets. There are two types of elsets in HyperMesh: components and entity sets. The Abaqus elsets that are linked to sectional property cards (such as *SOLID SECTION, *SHELL SECTION, etc.) become components in HyperMesh. Others become entity sets. To differentiate between these two types, there is a divider line "- - - - -" in the elset list that pops up if you click the element sets menu. The elsets listed below the divider line are components.

This dialog also contains a table for data line input. The table changes depending on the DLOAD type selected.

The table contains the following columns:

The Define tab for Define DLOAD on: Element sets contains the following buttons:

Review Set	Reviews the selected element sets by highlighting them in the HyperMesh graphics. Right-click Review to clear the review selections.
Create/Edit Set	Opens the Entity Sets panel in HyperMesh. When you finish creating/editing the set, click return. The Step Manager is updated with the new set appearing in the element set list.
Display/Review from panel	Opens the appropriate HyperMesh panel. Use the review button to expand the loads and constraints on the sets for visualization purposes.
	Add the selected element set from the pull down menu to the data line table on the right.
	Delete the selected element set from the data line table.
Show faces	This option is only shown for Default (pressure) type. It is mainly used to review the face identifiers of elements in the selected set. It creates a temporary skin of the selected elset, opens the Element Selector panel, from which you can select face elements from this skin. When you return from the element selector panel, the selected faces display color-coded face identifier tags. In performance graphics, these tags are sometimes blocked by the solid mesh. You may need to rotate the model a little to view the tags. Right-click the Show faces button to clear the face review.
Define by vector	This option is only shown for Gravity type. It opens the HyperMesh vector selector panel. Pick a vector and click proceed. This vector is used to define the Comp1, Comp2, Comp3, and Magnitude of the gravity load for the selected element set.
Create/Edit vector..	This option is only shown for Gravity type. Opens the Vectors panel in HyperMesh. When you finish creating/editing the vector, click return.
Review	For Default (pressure) type. Creates special review pressure loads in the HyperMesh graphics for the selected set. For other types, it reviews the selected element set. Right-click the Review button to clear the special review loads and highlighting.
Update	Updates the HyperMesh database with the data lines defined in the table. By default, HyperMesh does not create a display for loads defined with sets.
