This option allows the user to check and merge coincident nodes in the database. Coincident nodes are defined nodes having a distance between each other that is less than or equal to a specified tolerance.  eta/DYNAFORM merges all coincident nodes into the one with the lowest node ID number and sets all non-associated nodes as free nodes.

          Select an option in the displayed dialog box (all the nodes, the displayed nodes or the selected nodes in the model).

          Type the tolerance in the displayed dialog box.  eta/DYNAFORM prints the number of coincident nodes in the message prompt window and displays the eta/DYNAFORM Question dialog box asking the user to confirm the merge node operation.

          Select Yes to merge the coincident nodes.
