Basic meshing algorithms

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 and Netgen 1D-2D ) - Faces are split into triangular elements.

• Quadrangle meshing algorithm (Mapping) - Faces are split into quadrangular elements.

• For meshing of 3D entities (volume objects):

• Hexahedron meshing algorithm (i,j,k) - Volumes are split into hexahedral (cubic) elements.

• Tetrahedron (Netgen) meshing algorithm - Volumes are split into tetrahedral (pyramidal) elements.

There also is a number of more specific algorithms:

• for meshing by projection of another mesh

• for meshing geometrical objects with cavities

• for meshing prismatic shapes.

Constructing meshes page describes in detail how to apply meshing algorithms.
