3D Solid or Gasket Elements

Use the 3D solid or gasket elements option to define the *SURFACE card by specifying face identifiers for individual solid and gasket elements. These faces are displayed by special face elements.

In order to create surface, you need to select the underlying solid or gasket elements first.

Click Elements to open the Element Selector panel, and then select the underlying 3D solid or gasket elements from the graphic area. Selected elements are highlighted. Click Reset to resets the selected elements.

You can then define the face identifiers for the selected solids in two ways: (a) by creating a solid skin and manually picking the faces from the skin, (b) by picking nodes on a specific face and sweeping through a break angle. Under Select faces by, select Solid skin for (a) and Nodes on face for (b).

(a) Solid skin enables the following:

Button

Action

Faces

Creates a temporary skin of the selected solids. Opens the Element Selector panel, from which you can select face elements from this skin. The selected faces are highlighted. Click Reset to reset the selected faces and delete the skin.

Note:

by face on the element selector panel can be used to find all faces within a feature angle of the selected face. The feature angle setting can be accessed by clicking Preferences > Geometry Options.

The skin will initially have the same color as the current surface. You can change the skin color using Solid skin color button.

Add

Adds the selected faces to the current surface and creates special face elements for display. It also checks for duplicate faces and displays a message if any are found.

Note:

The Delete Face tab contains tools to find and delete duplicate faces in the current surface.

Reject

Rejects the recently added faces.

(b) Nodes on face enables the following:

Button

Action

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 solids.

Add

Finds all faces from the selected 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 create special face elements for display. It also checks for duplicate faces and displays a message if any are found.

Note:

The Delete Face tab contains tools to find and delete duplicate faces in the current surface.

Reject

Rejects the recently added faces.
