Preserve Node panel

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 Engineering Solutions 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.

The number of preserved nodes in your model is reported in the bottom-left corner of the panel.

Review Temporary and Free Nodes

You can also review temporary nodes in your model, and free nodes that are not referenced by any entities in your model in the Preserve Node panel. Free and temporary nodes are highlighted yellow in the graphics area.

In the Preserve Node panel you can convert free and temporary nodes into preserved nodes, which will be permanently saved in your model or a Solver deck. To convert a free node or a temporary node into a preserved node:

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

selected_free_node

2.	Click make preserved. The selected node is converted into a preserved node, and highlighted red.

3.	To reject this action, click reject.

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.

selected_free_node

2.	Click make temp. The selected node is converted into a temporary node, and highlighted yellow.

3.	To reject this action, click reject.

In the Preserve Node panel you can remove preserved nodes from your model. To delete preserved nodes:

1.	Select the nodes you with to remove from the graphics area. The selected nodes are highlighted white.

preserved_nodes_remove

2.	Click clear preserved.

preserved_nodes_remove2

3.	Optional: If you wish to remove all of the preserved nodes from your model, click clear all preserved.

Subpanels and Inputs

There are no subpanels in the Preserve Node panel. All inputs and command buttons are located in the main panel.

Input	Action
nodes selector	Use the selector to select the node(s) you want to convert into temporary or preserve node(s).
# of preserved nodes	Displays the total number of preserved nodes found in your model.

Input	Action
make temp	Converts the selected preserved or free nodes into temporary nodes.
make preserved	Converts the selected temporary or free nodes into preserved nodes.
clear preserved	Removes only the selected preserved nodes from your model.
clear all preserved	Removes all of the preserved nodes from your model.
reject	Reverts the most recent action you performed.
return	Exit to the previous panel.
