文档介绍：Edge and Face Meshing
Meshing - General
To reduce overall mesh size, confine small cells to areas where they are needed (., where high gradients are expected).
Controlling cell size distribution
Edges, Faces and Volumes can be directly meshed
A uniform mesh is generated unless pre-meshing or sizing functions are used.
Pre-meshing
Edge meshes can be graded (varying interval size on edge)
Graded edge mesh can be used to control distribution of cell size on face mesh.
Controlling distribution of cell size on face mesh also controls distribution of cell size in volume mesh.
Sizing Functions
Allow direct control of cell size distribution on edges, faces and volumes directly for automatic meshing.
Edge Meshing
Edge mesh distribution is controlled through the spacing and grading parameters.

Picking Edges for Meshing
Picking
Temporarily meshed edges
When you pick an edge, the edge is temporarily meshed using white nodes
Displayed edge mesh is based on current grading and spacing parameters
If you modify the scheme or spacing, the temporary mesh will be immediately updated
When you Apply, the mesh nodes will turn blue
Sense
Sense is used to show direction of grading
Every picked edge will show its sense direction using an arrow
The sense can be reversed by a shift-middle click on the last edge picked (this is in addition to the “next” functionality) or by clicking on the Reverse button
Soft Links
Picking and soft links
Pick with links
By enabling this option, Soft-linked edges can be selected in a single pick
Linked edges share the same information and can be picked in a single pick
Modifying soft links
You can anytime:
Form links
Break links
Maintain links
By default, GAMBIT will form links between unmeshed edges that are picked together
By default, GAMBIT will maintain links between meshed edges that
