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

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