Mesh Size Control

The same mechanisms as described in
Section Mesh Size Control (Sequential
Mesh Generation) are used for the mesh size control.
The local mesh size specification is extended by the mesh size extraction
from a region which has the form

where is the required mesh size at point
in the
region and are the mesh size specifications at Bezier control
points. The remaining variables have the the same meaning as in
Eq. (3.2). The adaptive mesh size specification is
based on a background parametric tree with the mesh size specification at
nodes and linear interpolation over the tree cells (segments,
quadrants, and octants). While the background tree is (typically) obtained from
the previous mesh generation process, the mesh size specification is
(typically) acquired from the previous analysis using the previous mesh.
Note that the adaptive mesh size control for the
parallel mesh generator is directly related to the underlying model.
