Disjointed meshes are often due to mesh generation of sub-domains of a single part which result in free nodes along internal edges. The Show Free Edges toggle displays free edges on the mesh. Such disjointed situations can be detected by finding pairs of nodes that are within a certain tolerance distance of each other. These nodes can then be combined using the Merge Duplicate Nodes button. Upon merging nodes within the user specified tolerance, an option to retain the largest or smallest node ID is available. By default the smaller node ID is retained.


  • Tolerance: Enter tolerance for finding duplicate nodes

  • rbs Keep smaller NID – Keep nodes with smaller node ID
  • rb Keep larger NID – Keep nodes with larger node ID
