Automatic Grading
Automatic gradation relieves the user from having to specify
numerous mesh densities
in order to obtain a smoothly graded mesh.
Typically, given a body to mesh,
the user only needs to assign mesh densities to the model entities
that are of interest to him,
letting the program
figure out
what the mesh densities should be anywhere else.
This feature is particularly attractive when small mesh densities have been
assigned to entities that are close to the interior of a model face,
where mesh
densities are difficult to set manually.
As for curvature-based meshing, an octree is used to control
the mesh densities.
- The methodology to control gradation comes from curvature-based meshing.
- An octree is used to smoothly grade the mesh sizes.
- The Delaunay mesher is used for surface meshing considering the tree
for any size query.

In this example, only the "legs" of the cell have been assigned mesh densities.
Any other seen mesh density comes from the automatic gradation feature.
