Element Based Surface: Delete Face Tab

Surfaces can be displayed in two ways: by special face elements or by contactsurfaces. The surfaces defined on 3D solid, gasket, shell, membrane, rigid elements are displayed by face elements while surfaces on 2D solid, axisymmetric, gasket and all beam, pipe, truss elements are displayed by contactsurfaces. In the Delete Face tab, delete faces or contactsurface from all elements types. It contains tools to find and delete duplicate faces for 3D solid, gasket, shell, membrane, or rigid elements.

There are three options for deletion: (a) All, or (b) By element, and (c) Duplicate faces.

contact_mgr_delete_face

(a) All enables the following:

Button	Action
Delete	Deletes all the faces or contactsurfaces in the current surface.

(b) By element enables the following:

Button	Action
Element Faces	Opens the Element Selector panel. For 3D solid, gasket, shell, membrane, and rigid elements, pick the faces (not the underlying elements). However, for 2D solid, axisymmetric, gasket or all beam, pipe, truss elements, pick the elements themselves as the contactsurfaces can not be picked from the graphic area. The corresponding Reset button resets the selected elements.
Delete	Deletes the selected faces or contactsurfaces from the selected 2D solid, axisymmetric, gasket, beam, pipe, truss elements.

Button

Action

Find Duplicate Faces

Finds duplicate faces, if any exists, for the current surface and highlights them in the graphic area. The status bar shows the number of duplicates found. The corresponding Reset button resets the selected elements.

Delete

Deletes the highlighted duplicate faces found.

Note:

Duplicate contactsurfaces cannot be added to the same surface in HyperMesh. Therefore, Duplicate Faces is only valid for 3D solid, gasket, shell, membrane, and rigid elements.
