The MESH module contains a set of meshing algorithms, which are used for meshing entities (1D, 2D, 3D) composing geometrical objects.
-
For meshing of 1D entities (edges):
-
Wire Discretisation meshing algorithm - splits a wire into a number of mesh segments following any 1D hypothesis.
-
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.
-
For meshing of 2D entities (faces):
-
Triangle meshing algorithms (Mefisto, Netgen 1D-2D and BLSUFR ) - Faces are split into triangular elements.
-
Quadrangle meshing algorithm (Mapping) - Faces are split into quadrangular elements.
-
Radial quadrangle 1D2D algorithm - Faces (circles or part of circles) are split into triangular and quadrangle elements.

Example of a quadrangular 2D mesh
-
For meshing of 3D entities (volume objects):
-
Hexahedron meshing algorithm (i,j,k) - Volumes are split into hexahedral (cubic) elements.
-
Tetrahedron (Netgen and GHS3D) meshing algorithms - Volumes are split into tetrahedral (pyramidal) elements.

- Note:
- BLSURF and GHS3D are commercial meshers and require a license to be used within the Mesh module.
There is also a number of more specific algorithms:
