Radial Prism

|
This algorithm applies to the meshing of a hollow 3D shape,
|
|
i.e. such shape should be composed of two meshed shells: an outer
|
|
shell and an internal shell without intersection with the outer
|
|
shell. One of the shells should be a :ref:`2D Projection <projection_2D>` of the other
|
|
shell. The meshes of the shells can consist both of triangles and
|
|
quadrangles.
|
|
|
|
The Radial Prism algorithm would fill the space between the two shells
|
|
with prisms.

|
This algorithm also needs the information concerning the number and
|
|
distribution of mesh layers between the inner and the outer shapes.
|
|
This information can be defined using either of two hypotheses:
|
|
|
|
.. image:: ../images/number_of_layers.png
|
|
:align: center
|
|
|
|
.. centered::
|
|
*"Number of layers"* hypothesis
|
|
|
|
.. image:: ../images/distribution_of_layers.png
|
|
:align: center
|
|
|
|
.. centered::
|
|
*"Distribution of layers"* hypothesis
|
|
|
|
*Distribution of layers* hypothesis allows using most of
|
|
:ref:`1D Hypotheses <a1d_meshing_hypo_page>` to define
|
|
the distribution of mesh layers.
