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