\n The MESH module contains a set of meshing algorithms, which are
|
||
|
|
used for meshing entities (1D, 2D, 3D) composing geometrical objects.
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>For meshing of 1D entities (<b>edges</b>):</li>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>Wire Discretisation meshing algorithm - splits a wire into a
|
||
|
|
number of mesh segments following any 1D hypothesis.</li>
|
||
|
|
<li>Composite Side Discretisation algorithm - allows to apply any 1D
|
||
|
|
hypothesis to a whole side of a geometrical face even if it is
|
||
|
|
composed of several edges provided that they form C1 curve, have the
|
||
|
|
same hypotheses assigned and form one side in all faces of the main
|
||
|
|
shape of a mesh.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<li>For meshing of 2D entities (<b>faces</b>):</li>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>Triangle meshing algorithms (Mefisto and Netgen 1D-2D ) - Faces
|
||
|
|
are split into triangular elements.</li>
|
||
|
|
<li>Quadrangle meshing algorithm (Mapping) - Faces are split into
|
||
|
|
quadrangular elements.</li>
|
||
|
|
</ul>

|
||
|
|
|
||
|
|
<li>For meshing of 3D entities (<b>volume objects</b>):</li>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>Hexahedron meshing algorithm (i,j,k) - Volumes are split into
|
||
|
|
hexahedral (cubic) elements.</li>
|
||
|
|
<li>Tetrahedron (Netgen) meshing algorithm - Volumes are split into
|
||
|
|
tetrahedral (pyramidal) elements.</li>
|
||
|
|
</ul>

There also is a number of more specific algorithms:

</ul>

\ref constructing_meshes_page "Constructing meshes" page describes in
|
||
|
|
detail how to apply meshing algorithms.
