\page prism_3d_algo_page 3D extrusion meshing algorithm
|
|
|
|
3D extrusion algorithm can be used for meshing prisms, i.e. <b>3D Shapes</b>
|
|
defined by two opposing faces having the same number of vertices and
|
|
edges and meshed using, for example, the \ref projection_algos_page
|
|
"2D Projection" algorithm. These two faces should be connected by
|
|
quadrangle "side" faces.
|
|
|
|
The opposing faces can be meshed with either quadrangles or triangles,
|
|
while the side faces should be meshed with quadrangles only.

|
|
As you can see, the <b>3D extrusion</b> algorithm permits to build and to
|
|
have in the same 3D mesh such elements as hexahedrons, prisms and
|
|
polyhedrons.
|
|
|
|
\note This algorithm works correctly only if the opposing faces have
|
|
the same (or similar) meshing topography. Otherwise, 3D extrusion
|
|
algorithm can fail to build mesh volumes.
