# Introduction to MESH

MESH module of SALOME is destined for:

- import and export of meshes in MED format,

- meshing geometrical models previously created or imported by the GEOM component. MESH module allows to apply 1D, 2D, 3D meshing algorithms and a set of hypotheses:

- Arithmetic 1D

- Average Length

- Deflection 1D

- Number of segments

- Start and end length

- Automatic Length

- Max Element Area

- Length from Edges

- Quadrangle Preference

- Max Element Volume

- modification of locally generated meshes by

- Addition of nodes and elements

- Removal of nodes and elements

- grouping mesh elements and performing operations on these groups

- quality control of meshes basing on a set of definite criteria -

for edges:

- Length of edges

- Borders at multi-connection

- Free borders

for faces:

- Area

- Free edges

- Borders at multi-connection 2D

- Length 2D

- Minimum angle

- Taper

- Aspect Ratio

- Warping

- Skew

for solids:

- Aspect ratio 3D

- Volume
