When the 2D Mesh module is active, the Mesh menu becomes available. The Mesh menu has two submenus: Convert To and Advanced. 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.
- Z Values → Dataset
- Creates a dataset from the Z locations of the nodes.
- Map to Z Values
- Moves the Z locations of the nodes to the values in the dataset.
- Zoom To Extents
- Frames the Graphics Window around the selected objects.
A new 2D scatter point set is created from the 2D mesh nodes.
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.
Used to convert triangular elements into quadratic elements.
Used to convert quadrilateral elements into triangular elements.
Inserts the node strings into the mesh as a new edge, creating new elements and nodes.
Converts linear elements to quadratic and quadratic elements to linear.
Subdivides elements into smaller elements.
- Relax Elements...
Moves mesh nodes in order to improve the quality (element shape and size) of the mesh.
Creates a 3D mesh consisting of tetrahedron from the 2D mesh.
- Export
Exports a 2D mesh to a file (*.2dm, *.fem etc).
