/*! \page smeshpy_interface_page Python interface Python package smesh defines several classes, destined for easy and clear mesh creation and edition. Documentation for smesh package is available in two forms: The structured documentation for smesh package, where all methods and classes are grouped by their functionality, like it is done in the GUI documentation and the \ref smeshDC "linear documentation for smesh package" grouped only by classes, declared in the smesh.py file. The main page of the \ref smeshDC "linear documentation for smesh package" contains a list of data structures and a list of functions, provided by the package smesh.py. The first item in the list of data structures (\ref smeshDC::smeshDC "class smesh") also represents documentation for the methods of the package smesh.py itself. The package smesh.py provides an interface to create and handle meshes. Use it to create an empty mesh or to import it from the data file. Once a mesh has been created, it is possible to manage it via its own methods, described at \ref smeshDC::Mesh "class Mesh" documentation (it is also accessible by the second item "class Mesh" in the list of data structures). Class \b Mesh allows assigning algorithms to a mesh. Please note, that some algorithms, included in the standard SALOME distribution are always available: - REGULAR (1D) - COMPOSITE (1D) - MEFISTO (2D) - Quadrangle (2D) - Hexa(3D) - etc... To add hypotheses, use the interfaces, provided by the assigned algorithms. Below you can see an example of usage of the package smesh for 3d mesh generation. \anchor example_3d_mesh

Example of 3d mesh generation:

\code from geompy import * import smesh ### # Geometry: an assembly of a box, a cylinder and a truncated cone # meshed with tetrahedral ### # Define values name = "ex21_lamp" cote = 60 section = 20 size = 200 radius_1 = 80 radius_2 = 40 height = 100 # Build a box box = MakeBox(-cote, -cote, -cote, +cote, +cote, +cote) # Build a cylinder pt1 = MakeVertex(0, 0, cote/3) di1 = MakeVectorDXDYDZ(0, 0, 1) cyl = MakeCylinder(pt1, di1, section, size) # Build a truncated cone pt2 = MakeVertex(0, 0, size) cone = MakeCone(pt2, di1, radius_1, radius_2, height) # Fuse box_cyl = MakeFuse(box, cyl) piece = MakeFuse(box_cyl, cone) # Add to the study addToStudy(piece, name) # Create a group of faces group = CreateGroup(piece, ShapeType["FACE"]) group_name = name + "_grp" addToStudy(group, group_name) group.SetName(group_name) # Add faces to the group faces = SubShapeAllIDs(piece, ShapeType["FACE"]) UnionIDs(group, faces) ### # Create a mesh ### # Define a mesh on a geometry tetra = smesh.Mesh(piece, name) # Define 1D hypothesis algo1d = tetra.Segment() algo1d.LocalLength(10) # Define 2D hypothesis algo2d = tetra.Triangle() algo2d.LengthFromEdges() # Define 3D hypothesis algo3d = tetra.Tetrahedron() algo3d.MaxElementVolume(100) # Compute the mesh tetra.Compute() # Create a groupe of faces tetra.Group(group) \endcode Examples of Python scripts for all Mesh operations are available by the following links: - \subpage tui_creating_meshes_page - \subpage tui_cartesian_algo - \subpage tui_viewing_meshes_page - \subpage tui_defining_hypotheses_page - \subpage tui_quality_controls_page - \subpage tui_filters_page - \subpage tui_grouping_elements_page - \subpage tui_modifying_meshes_page - \subpage tui_transforming_meshes_page - \subpage tui_notebook_smesh_page - \subpage tui_measurements_page - \subpage tui_generate_flat_elements_page - \subpage tui_work_on_objects_from_gui */
