then converted to the single node.

To merge nodes of your mesh:

-sub-menu select the Merge nodes item. The following dialog box
-shall appear:

- \b Automatic or \b Manual mode allows choosing how the nodes are

+ detected by the program and/or select any nodes to be merged.
- \b Tolerance is a maximum distance between nodes sufficient for
merging.
-- Exclude Groups group box allows to ignore the nodes which
-belong to the specified mesh groups.

- Activation of No merge of corner and medium nodes of quadratic

+ elements with corner nodes. This check-box is enabled provided
+ that the selected mesh includes quadratic elements.
+- Exclude groups from detection group allows to ignore the
+ nodes which belong to the specified mesh groups. This control is
+ active provided that the mesh includes groups.
+- Nodes to keep during the merge 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.
+
+ - \a Selection button activates selection of nodes to keep.
+ - Nodes button activates selection of nodes in the
+ Viewer.
+ - Groups and sub-meshes button activates selection of
+ groups and sub-meshes.
+ - \b Add button adds selected nodes or groups to the list.
+ - Nodes or groups selected in the list can be removed using \b
+ Remove button.

- Automatic mode:
-- In the \b Automatic Mode all Nodes within the indicated tolerance

+In this mode additional controls are available:
-- \b Detect button generates the list of coincident nodes for the given
