Displaying nodes independently of elements

You can control the visibility of the nodes of a mesh independently of the elements. When you select the Show and Hide Nodes Independently check box in the Model Display dialog box, you can then use the standard Show and Hide commands to show or hide nodes. For example, you can place a selection of nodes into a group and then use the Show Only command to display only that group of nodes, without displaying the elements. This ability gives you more detailed control over the display of your finite element model.

Note:

Nodes appear in the graphics window only when the Marker Type in the Model Display dialog box is set to one of the display options such as Asterisk.

Nodes display type in the Show and Hide dialog box

When the Show and Hide Nodes Independently option is selected, the Nodes display type becomes available in the Show and Hide dialog box. This option lets you show or hide all nodes in the model.

The following graphic shows a model display when the mesh is set to Hide and the nodes are set to Show in the Show and Hide dialog box.

Show and Hide commands for nodes

When the Show and Hide Nodes Independently check box is selected, two commands become available. These commands let you add nodes to the display when you use the Show and Hide or Show Only commands to display only elements.

• Show Exterior Nodes—Displays the nodes on the free faces of the displayed elements.

• Show Nodes—Displays all nodes that are attached to the displayed elements.

Note:

As soon as you select one of these commands, nodes are displayed until you hide them again (for example, by using the Show and Hide command). You cannot select Show Exterior Nodes and Show Nodes again to re-hide the nodes.

(1) Only elements displayed; (2) Show Exterior Nodes; (3) Show Nodes

Show and Hide preferences for meshes

When the Show and Hide Nodes Independently check box is selected, an additional mesh display preference named Show and Hide Meshes becomes available in the Model Display dialog box. This preference applies to the Show and Hide commands that control the display of meshes. It sets your preferences for whether those commands should include or exclude the nodes, and whether they should include all mesh nodes or only exterior nodes.

• Include all mesh nodesUse this preference, for example, to hide all nodes of a mesh when you hide that mesh.

• Include exterior mesh nodesUse this preference, for example, to display only the exterior nodes on free element faces when you show a mesh.

• Do not include nodesUse this preference, for example, to leave all the nodes of a mesh displayed when you hide that mesh.
