-
-This functionality allows user to detect groups of coincident nodes
-with specified tolerance; each group of the coincident nodes can be
-then converted to the single node.

-<em>To merge nodes of your mesh:</em>
-<ol>
-<li>Choose \b Modification -> \b Transformation -> <b>Merge nodes</b>
- menu item. The following dialog box shall appear:</li>
-<br>
-\image html mergenodes_auto.png
-<br>
-<ul>
-<li>\b Name is the name of the mesh whose nodes will be merged.</li>
-<li>\b Automatic or \b Manual mode allows choosing how the nodes are
- processed. In \b Manual mode you can adjust groups of coincident nodes
- detected by the program and/or select any nodes to be merged.</li>
-<li>\b Tolerance is a maximum distance between nodes sufficient for
-merging.</li>
-<li>Activation of <b>No merge of corner and medium nodes of quadratic
- cells</b> check-box prevents merging medium nodes of quadratic
- elements with corner nodes. This check-box is enabled provided
- that the selected mesh includes quadratic elements.</li>
-<li>Activation of <b>Avoid making holes</b> check-box prevents merging
- nodes that make elements invalid (but not degenerated) and hence
- removed. Thus, no holes in place of removed elements appear. </li>
-<li><b>Exclude groups from detection</b> group allows to ignore the
- nodes which belong to the specified mesh groups. This control is
- active provided that the mesh includes groups.</li>
-<li><b>Nodes to keep during the merge</b> group allows to specify
- nodes to keep in the mesh. (By default a node being the first in a
- group of coincident nodes is kept.) It is possible to either select
- nodes in the Viewer or select groups of any element type whose nodes
- will be kept.
- <ul>
- <li>\a Selection button activates selection of nodes to keep.</li>
- <li><b>Nodes</b> button activates selection of nodes in the
- Viewer.</li>
- <li><b>Groups and sub-meshes</b> button activates selection of
- groups and sub-meshes.</li>
- <li>\b Add button adds selected nodes or groups to the list.</li>
- <li> Nodes or groups selected in the list can be removed using \b
- Remove button.</li>
- </ul>
-</li>
-</ul>
-
-<li><b>Automatic mode:</b>
-<br>
-<ul>
-<li>In the \b Automatic Mode all nodes within the indicated tolerance
-will be merged. The nodes which belong to the groups specified in
-<b>Exclude groups from detection</b> will NOT be taken into account.</li>
-</ul>
-</li><br>
-<li> The \b Manual mode gives you full control of what the operation will do.
-In this mode additional controls are available:
-<ul>
- <li>\b Detect button generates the list of coincident nodes for the given
- \b Tolerance.</li>
- <li><b>Coincident nodes</b> is a list of groups of nodes for
- merging. Upon \b Apply all nodes of each group will
- be united into one node. The first node of a group is kept and
- the others are removed. By default the first node has a lowest ID
- within the group.
-<ul>
-<li>\b Remove button deletes the selected group from the list.</li>
-<li>\b Add button adds to the list a group of nodes selected in the
-viewer.</li>
-<li><b>Select all</b> check-box selects all groups.</li>
-<li><b>Show double nodes IDs</b> check-box shows/hides identifiers of
-nodes of selected groups in the 3D viewer.</li>
-</ul>
-

-</li>
- <li><b>Edit selected group of coincident nodes</b> list allows
- editing the selected group:
- <br><br>
- \image html add.png
- <center>adds to the group the nodes selected in the viewer.</center>
- <br>
- \image html remove.png
- <center>removes from the group the selected nodes.</center>
- <br>
- \image html sort.png
- <center>moves the selected node to the first position in the
- group in order to keep it in the mesh.</center><br>
- </li>
-</ul>
-</li>
-<li>To confirm your choice click \b Apply or <b>Apply and Close</b> button.</li>
