Analysis page

Unused free nodes in a model that you would like to keep for future use are called preserved nodes. When a free node is not referenced by any of the entities in your model, unused nodes are automatically deleted. You can save a free node that you are not currently using by converting it into a temporary node, but HyperMesh will only continue to save these free nodes as long as they are marked as a temporary node. To guarantee that a free or temporary node will be saved in your model once you create them, you must convert them into a preserved node.

Review Preserved Nodes

When you open or import a model that contains preserved nodes, you can only review these nodes in the Preserve Node panel. Preserved nodes are highlighted red in the graphics area.

In the Preserve Node panel you can convert free and preserved nodes into temporary nodes, which will only be saved as long as they are marked as a temporary node. To convert a free or preserved node into a temporary node:

1.	Select the free or preserved node in the graphics area. The selected node is highlighted white.
