Merging nodes

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.

Merge nodes button

To merge nodes of your mesh:

1. From the Modification choose Transformation and from its sub-menu select the Merge nodes item. The following dialog box shall appear:
   

   

   
   

   • Name is the name of the mesh whose nodes will be merged.
   • Automatic or Manual Mode allows choosing how the nodes are processed.
   • 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.

2. Automatic mode:
   
   • In the Automatic Mode all Nodes within the indicated tolerance will be merged. The nodes which belong to the groups specified in the Exclude Groups will be not taken into account.
   
   
3. If the Manual Mode is selected, additional controls are available:
   • Detect button generates the list of coincident nodes for the given Tolerance.

   • Coincident nodes is a list of groups of nodes for merging. All nodes of each group will form one after the operation.

     • Remove button deletes the selected group from the list.
     • Add button adds to the list a group of nodes selected in the viewer with pressed "Shift" key.
     • Select all checkbox selects all groups.

     
     

     

     
     

   • Edit selected group list allows editing the selected group:
     
     
     
     adds to the group the node selected in the viewer.
     
     
     removes from the group the selected node.
     
     
     moves the selected node to the first position in the group. This means that all other nodes will be merged into this one.
     
4. To confirm your choice click Apply or Apply and Close button.
