When the 2D Mesh module is active, the Mesh menu becomes available. Below is a list of all commands in the Mesh menu:

  • New 2D Mesh
    Creates a new, empty 2D mesh.
  • 2D Mesh Settings...
    Opens the 2D mesh settings which include: default z values for new nodes, options for deleting triangles etc.
  • Lock All Nodes
    Since it is possible to accidentally drag points, nodes can be "locked" to prevent them from being dragged or edited by toggling on this command.
  • Find Element...
    Selects an element given the element ID.
  • Find Node...
    Selects a node given the node ID.
  • Triangulate
    Creates triangular elements from all or selected nodes using the Delauney criteria. If triangles already exist, they will be deleted.
  • Renumber
    Renumbers mesh nodes eliminating gaps in numbering. Optionally a node string can be created and used to guide the renumbering.
  • Convert To
    • Mesh → 2D Scatter Points
      A new 2D scatter point set is created from the 2D mesh nodes.
    • Mesh → TIN
      A new TIN is created from the 2D mesh.
    • Contours → Arcs
      Creates a new coverage containing feature arcs derived from the linear contours displayed on the 2D mesh.
  • Advanced
    • Select Thin Triangles
      Selects triangles which meet the "thin triangle aspect ratio" specified in the 2D mesh settings.
    • Find Duplicate Nodes...
      Selects nodes that are close to each other within a user specified tolerance.
    • Merge Triangles
      Used to convert triangular elements into quadratic elements.
    • Split Quadrilaterals
      Used to convert quadrilateral elements into triangular elements.
    • Add Breaklines
      Inserts the node strings into the mesh as a new edge, creating new elements and nodes.
    • Convert Elements
      Converts linear elements to quadratic and quadratic elements to linear.
    • Refine Elements
      Subdivides elements into smaller elements.
    • Relax Elements...
      Moves mesh nodes in order to improve the quality (element shape and size) of the mesh.
    • Mesh → 3D Tets
      Creates a 3D mesh consisting of tetrahedron from the 2D mesh.
    • Export
      Exports a 2D mesh to a file (*.2dm, *.fem etc).
