3D Solid Coated with Shell

In HyperMesh, surfaces on 3D solid or gasket elements that are coated with shell, membrane, or rigid elements are treated differently from surfaces on regular solids. Use the 3D solid coated with shell option to define the *SURFACE card by specifying face identifiers for these 3D solid or gasket elements. The faces are displayed by special contactsurface elements. Unlike, regular solids, there is only one way to define the face identifiers for solids with shell coating: by picking nodes on a specific face and sweeping through a break angle. Therefore, the Nodes on face option is always selected. This option is valid for Standard.3D template or 3D models in Explicit template only.

3D solid coated with shell enables the following:

Button

Action

Elements

Opens the Element Selector panel, from which you can select underlying 3D solid and gasket elements from the graphic area. The selected elements are highlighted. The corresponding Reset button resets the selected elements.

Nodes

Opens the Node Selector panel, from which you can select nodes from the graphic area. Three nodes (or two corner nodes) from the same solid element must be picked to define a face of that solid. The selected nodes are highlighted. The corresponding Reset button resets the selected nodes.

Note:

Several three-node or two-corner-node sets can be selected at the same time to define faces in different elements.

Add

Finds all faces from the selected 3D solids that fall within a specified break angle of the face(s) defined by nodes. These faces are then added to the current surface and special contactsurface elements are created for display.

Note:

You cannot add duplicate contactsurfaces for the same element in HyperMesh. Therefore, the Add button does not check for duplicates and there is no Reject button.
