Detailed Description

This class allows defining and managing a mesh.

It has a set of methods to build a mesh on the given geometry, including the definition of sub-meshes. It also has methods to define groups of mesh elements, to modify a mesh (by addition of new nodes and elements and by changing the existing entities), to get information about a mesh and to export a mesh in different formats.

Note

Some methods are dynamically added to the Mesh class in runtime by meshing plug-in modules. If you fail to find help on some methods in the documentation of SMESH module, try to look into the documentation for the meshing plug-ins.
