# Introduction to SMESH

SMESH 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. SMESH module allows to apply 1D, 2D, 3D meshing algorithms and a set of hypotheses:

- Local length

- Number of segments

- Max Element Area

- Max Element Volume

- modification of locally generated meshes by

- Addition/deletion of nodes and elements

- Moving 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-connections

- Free borders

for faces:

- Area of elements

- Minimum angle

- Taper

- Aspect Ratio

- Warping

- Skew angle
